This study is based on a research project on the field of urban regeneration of the old<br />

historical region of Istanbul named Galata, where the Golden Horn meets the Bosphorus.<br />

The district, which is accepted as a part of the world’s cultural heritage, has a history<br />

bearing the architectural, cultural <strong>and</strong> religious traces of Genovese, Byzantine <strong>and</strong> Ottoman<br />

civilizations. In spite of the active pattern in the south <strong>and</strong> in the north, Galata<br />

is a blighted area stuck between these regions. Although Galata has to play a significant<br />

role by both its location in Istanbul <strong>and</strong> its history, the area has been losing its value<br />

rapidly. The area is continuously destroyed because of the lack of care <strong>and</strong> also due to<br />

user’s damage. There is a need <strong>for</strong> new researches <strong>and</strong> proposals in order to find out the<br />

reasons <strong>for</strong> the physical <strong>and</strong> social collapse of the region.<br />

The study has adopted the basic concepts <strong>and</strong> methods of Space Syntax to develop a<br />

regeneration strategy <strong>for</strong> Galata by:<br />

• Objectively analyzing the urban <strong>for</strong>m of Galata <strong>and</strong> measuring levels of spatial<br />

integration within the local <strong>and</strong> wider urban context,<br />

• Gathering objective data on people’s activities, especially the patterns of everyday<br />

pedestrian movement <strong>and</strong> space use,<br />

• Analyzing the relation between urban <strong>for</strong>m <strong>and</strong> the pattern of movement <strong>and</strong> space<br />

use,<br />

• <strong>Study</strong>ing the patterns of l<strong>and</strong> use <strong>and</strong> building use in the historic core of Galata,<br />

• Generating strategic design proposals, which enhance the physical connections with<br />

the surroundings <strong>and</strong> integrate people with new <strong>and</strong> existing facilities,<br />

• Accessing the likely effects of design proposals on pedestrian activity, <strong>and</strong> the likely<br />

effects of this on the wider process of regeneration.<br />

Through an objective assessment of the problems <strong>and</strong> constraints of the historic core<br />

the Space Syntax study has identified possible physical design solutions, which could<br />

enhance the functioning of the historic, <strong>and</strong> decrease its isolation from the rest of the town<br />

center. The fundamental aim in these proposals is to turn what is currently an unpleasant,<br />

derelict area to a new active zone without losing its historical character. Thus the historic<br />

core of Galata would have a better opportunity of attracting activity, investment <strong>and</strong><br />

socio-economic gain. In return, the historic core would provide a key attraction <strong>and</strong> a<br />

focal point of heritage <strong>and</strong> identity within Galata, which would consequently influence<br />

other parts of the town center <strong>and</strong> benefit the wider Istanbul context.<br />

It’s believed that this project will contribute modern trends <strong>and</strong> draw lessons <strong>for</strong> future<br />

policy <strong>and</strong> practice.

1. Introduction<br />

Ferryboats sail to <strong>and</strong> from the ports around <strong>and</strong> under the Galata Bridge, connecting<br />

the center of the city to its maritime suburbs on the Bosphorus <strong>and</strong> Mediterranean. A<br />

stream of pedestrian <strong>and</strong> vehicular traffic pours across the Galata Bridge <strong>and</strong> along the<br />

highways that parallels the right <strong>and</strong> left banks of the Golden Horn (Figure 281).<br />

However, instead of being a focus <strong>for</strong> pedestrian activity in the area, the spaces in the<br />

Galata area are largely empty <strong>for</strong> most of the day, thus creating the area dangerous <strong>for</strong><br />

pedestrians. As a consequence, business, shopping <strong>and</strong> entertainment activities facing the<br />

streets of the area have had difficulty in trading which do not seem from their “central”<br />

location. Despite the lively neighborhood, Galata remains disjointed <strong>and</strong> rigidly separated<br />

according to the l<strong>and</strong>-use, <strong>and</strong> this historical site of Istanbul is in the process of deterioration.<br />

It is exactly this imbalance between the neighboring areas that the “Space Syntax”<br />

study has aimed to redress. This study is supported by the Greater City Municipality of<br />

Istanbul <strong>and</strong> Urban & Environmental Planning & Research Center of Istanbul Technical<br />

University. The project group, Dr. Kayvan Karimi <strong>and</strong> Tim Stonor as consultants of Space<br />

Syntax Ltd. <strong>and</strong> Space Syntax laboratory of UCL, are commissioned to undertake a Space<br />

Syntax study of urban <strong>for</strong>m <strong>and</strong> pedestrian activity <strong>and</strong> to develop planning <strong>and</strong> design<br />

proposals <strong>for</strong> Galata.

2. Aim<br />

The fundamental aim of the project that is subject to this paper is rehabilitation <strong>and</strong><br />

trans<strong>for</strong>mation of the historic Galata which is a part of Istanbul’s CBD, while providing<br />

a proper relationship of spatial layout <strong>and</strong> structural network within the metropolitan<br />

city. Following matters are taken into consideration to benefit from a model that explains<br />

human settlements through human behavior:<br />

• To turn what is currently an unpleasant, derelict area to a new active zone without<br />

losing its historical character <strong>and</strong> making the historical Galata a part of the activity<br />

center, as well a “live center”;<br />

• Integrating Galata with the spatial structure of the whole city <strong>and</strong> increasing its<br />

relations with the other parts of the city, especially with the larger city centers such<br />

as Besiktas, Taksim, Sisli <strong>and</strong> so on;<br />

• To increase vitality <strong>and</strong> to create an economically productive historic core without<br />

harming the traditional character of the city;<br />

• To turn out the north-south link to a well-used route between the Beyoglu - Pera<br />

<strong>and</strong> Karakoy waterfront area;<br />

• To recreate <strong>and</strong> strengthen a continuance of Istiklal Street between Galata Square<br />

<strong>and</strong> Galata Bridge;<br />

• To give new functions to the main street lined with historical facades, namely “Hendek<br />

Street” which is opening to a piazza where Galata tower, is located;<br />

• To create a pedestrian link between the underground station <strong>and</strong> the Galata Tower,<br />

which is one of the l<strong>and</strong>marks of Istanbul<br />

• To prepare a renewal project <strong>for</strong> creating attractiveness in the site by using the<br />

historical features of Galata.<br />

3. <strong>Study</strong> area<br />

Throughout history, Galata bridges have always connected the two shores of the Golden<br />

Horn. Galata is 1300m from Taksim Square, which is accepted as the center of Beyoglu<br />

<strong>and</strong> Pera, <strong>and</strong> also the hub of the modern town. Thus Galata Bridge plays an important<br />

role by connecting old Istanbul (Eminonu District) to the new (Karakoy <strong>and</strong> Beyoglu<br />

districts). Karakoy Port is connected to the Tunel Square by an underground rail system,<br />

which is one of the oldest in the world. At one end of the Galata Bridge there is Eminonu,<br />

which is the focal point of Istanbul’s colorful daily life <strong>and</strong> at the other end Karakoy,<br />

which is popular because of commercial <strong>and</strong> banking facilities. The main street lined with<br />

historical facades, namely “Hendek Street” is opening to a piazza where Galata Tower is<br />

located. The Galata Tower is one of the l<strong>and</strong>marks that were built by the Genoese in 1348<br />

<strong>and</strong> the apex of the Genovese <strong>for</strong>tifications of medieval Galata.

4. Methodology<br />

The movement patterns of the historical Galata region of Istanbul, which has been shaped<br />

under various cultures, <strong>and</strong> which is still the commercial core of Istanbul, will be defined<br />

through the method of “space syntax”, which analyses the global <strong>for</strong>ms of the settlements<br />

by mathematical interpretations.<br />

Space Syntax is a technique that can be used <strong>for</strong> morphological analyses of buildings,<br />

architectural plans, urban areas <strong>and</strong> urban plans. Space syntax is also one of the few<br />

theories which allow us to underst<strong>and</strong> how culture <strong>and</strong> society are embedded in the specific<br />

relational patterns constituting architecture, urban design <strong>and</strong> urban planning.<br />

The Space Syntax study of Galata’s historic core has generated a multi-level, electronic<br />

database of urban <strong>for</strong>m <strong>and</strong> function, containing: axial maps, spatial integration <strong>and</strong><br />

movement pattern.<br />

5. Analysis<br />

5.1. Spatial Maps<br />

Besides historical documents, the traditional surveys <strong>for</strong> analyzing the project area are<br />

prepared. These surveys have been complemented by preparing “a spatial model” of Galata<br />

explaining the existing structure. These syntactic maps can give some idea on the accessibility<br />

of pedestrian linkages through the area. This work on syntactic analyses has shown<br />

that; Voyvoda <strong>and</strong> Kemeralti streets are the most spatially integrated lines in historical<br />

Galata, <strong>and</strong> Hendek Street is the next most integrated street.<br />

When Taksim square is included in the analyses; Istiklal Street, which is the busiest<br />

street, is defined as the most spatially integrated lines. The effects of pedestrian movements<br />

in Persembe Pazari, on Bankalar Street <strong>and</strong> on the Karakoy port are not defined as<br />

integrated spaces on this map.<br />

The streets <strong>and</strong> spaces, which are close to the Karakoy, Eminonu ports <strong>and</strong> the Galata<br />

Bridge, are explained as the focus of the activity areas, which define the actual situation<br />

of the site. The spine of Beyoglu-Pera district, Istiklal Street, which is a pedestrian strip,<br />

is defined as the next most integrated lines.<br />

5.2. Pedestrian <strong>Movement</strong> Analyses<br />

The first stage of the study is concentrated on the observations of how people <strong>and</strong> vehicles<br />

are flowing through the Galata area at present. This has been done by counting flow rates<br />

at numerous locations in <strong>and</strong> around Galata; ’tracking’ pedestrian routes across the area<br />

<strong>and</strong> recording local l<strong>and</strong> use patterns. A survey of pedestrian activity has been carried<br />

out both in weekday <strong>and</strong> weekends <strong>for</strong> five different categories of people (adult men, adult<br />

women, elderly, teenagers, <strong>and</strong> children). Pedestrian movement levels were recorded at 263<br />

locations on eight different regions due to the functions. The observations were carried<br />

out on 29 May 2003 <strong>and</strong> on 31 May 2003. Each location was observed from 08:00 to 20:00.<br />

Some significant findings are:<br />

1. The study area is a man-dominant area (about half of the overall movement is<br />

generated by men). This becomes more evident on weekday.<br />

2. There are more than 1.500.000 people in the area during the day (weekday). The<br />

number is about 1.100.000 on weekend.

Historical Galata District 569<br />

3. The max. movement is in the afternoon both on weekday <strong>and</strong> weekend.<br />

5.3. Pedestrian <strong>Activity</strong> Schemas<br />

In order to have an opinion of the most commonly used routes, pedestrians have been followed<br />

<strong>and</strong> their routes have been recorded. The pedestrians are recorded in two categories:<br />

inhabitants <strong>and</strong> tourists.<br />

Relations between Pedestrian <strong>Movement</strong> <strong>and</strong> the Spatial Configuration are examined in<br />

order to underst<strong>and</strong> the actual movement potentials of the site <strong>and</strong> also to test the design<br />

proposal. Although the movement analyses have covered most street segments in the study<br />

area, these records give only the number of pedestrians; they don’t give any in<strong>for</strong>mation<br />

about the routes of the movement. In order to get this in<strong>for</strong>mation, “pedestrian tracking”<br />

study has been carried out. The routes of the pedestrians who have entered the area from<br />

specific gates like port, subway or bus station have been recorded on the base map of the<br />

area. Analyzing followings do not only test the results of the movement analyses, but they<br />

also give an idea about which side of a walkway is used more frequently. The observations<br />

allow us to classify the results according to gender <strong>and</strong> time period.<br />

The pattern that is generated by the inhabitants is found very similar with the pattern<br />

of the spatial integration analyses (Figure 282). The intense movement pattern on Istiklal<br />

Street, Kadikoy Port, Bankalar Street, hardware stores region, Kemeralti Street <strong>and</strong><br />

Sishane Square clearly designates this similarity. There are also differences such as the<br />

movement on Yolcuzade Iskender Street <strong>and</strong> on Mesrutiyet Street. This situation reflects<br />

the effect of the l<strong>and</strong> uses on the movement activities.<br />

The movement pattern of the tourists is different then the inhabitants’ <strong>and</strong> the movement<br />

pattern is also independent from the l<strong>and</strong> uses of the site (Figure 283). The beginning<br />

<strong>and</strong> ending points of their routes are the places, which are more attractive <strong>for</strong> the tourists,<br />

such as Istiklal Street, Eminonu region or Galata Tower. Even though there is a northsouth<br />

movement in the area, the movement generally stems from Istiklal Street. There are<br />

two common routes; 1. Taksim - Galata Tower <strong>and</strong> its surroundings - Taksim; 2. Eminonu<br />

- Galata Tower <strong>and</strong> its surroundings - Eminonu.<br />

5.4. Relations between Pedestrian <strong>Movement</strong> <strong>and</strong> the Spatial Configuration<br />

In this study, the area was examined in 7 different regions, which were determined according<br />

to their functions.<br />

Even though the study area is stinted with Galata Tower, its surroundings <strong>and</strong><br />

Hendek Street; in order to analyze the effects of the movement patterns on the<br />

area, spatial integration analyses of Whole Galata, Taksim+Tarlabasi+Galata, Taksim+Tarlabasi+Galata+Eminonu<br />

<strong>and</strong> Taksim+Tarlabasi+Galata+Historical Peninsula,<br />

have been made.<br />

But, only the data of the analysis that comprehends Galata area <strong>and</strong> Taksim+Tarlabasi+Galata<br />

area have been used to study the relation between the spatial<br />

integration values <strong>and</strong> the current movement levels. The data of 165 street segments have<br />

been used. In calculating this correlation, when the correlation number was lower than<br />

desired, its reasons have been analyzed with the results of the regression analyses, then a<br />

statistical method that depends on ignoring the values that are out of the min. <strong>and</strong> max.<br />

limits (st<strong>and</strong>ard deviation), has been carried out.

5.5. Results of the Analyses<br />

As a result of the analyses these basic remarks can be pointed out:<br />

• In historical periods there were strong connections between Galata Square <strong>and</strong> the<br />

ports, which can also be seen in historical maps. Currently, these links have been<br />

disappeared.<br />

• The center of activity has shifted from the historical core of Galata, towards Istiklal<br />

Street in the north <strong>and</strong> Karakoy Port in the south.<br />

• The streets where mostly commercial <strong>and</strong> finance functions are located, are defined<br />

to have the highest spatial integration values in the area. Hendek Street, which has<br />

offices <strong>and</strong> service function on the ground floors <strong>and</strong> mostly residential use on upper<br />

floors, is secondary when it is evaluated with the movement it attracts.<br />

• The movement pattern of Galata is so weak that it nearly separates the Karakoy<br />

<strong>and</strong> Istiklal Street regions<br />

• In Galata region, especially on <strong>and</strong> around Hendek Street the levels of movement<br />

are very low.<br />

• Although Galata is near the areas that have banking, office, service, retail functions<br />

<strong>and</strong> the seashore, it is very segregated from those areas, in means of both visual <strong>and</strong><br />

physical contact.<br />

• The movement in Galata region mostly depends on daily trips in the areas where<br />

retail <strong>and</strong> finance functions are located.<br />

• On weekday there is a noticeably high pedestrian movement that stems from expertise,<br />

(e.g., lighting accessories stores).<br />

• Significant design decisions should be made in order to attract movement towards<br />

Galata region (from Istiklal <strong>and</strong> Galip Dede streets).<br />

• Although the movement rates that have been generated by the Karakoy Port are<br />

very high, the spatial model of the port area seems to be weak to carry that much<br />

movement. So, it can be said that the location of the Karakoy Port is wrong <strong>and</strong> a<br />

new port area needs to be designed with sufficient capacity to collect <strong>and</strong> distribute<br />

the pedestrian movement.<br />

• Geometrical arrangements about existing vehicle+pedestrian axes that lead to<br />

Karakoy Square should be made, in favor of pedestrians.<br />

• According to the observations, Galip Dede <strong>and</strong> Yuksek Kaldirim streets, which connect<br />

Istiklal Street <strong>and</strong> Karakoy Square, have high movement levels both on weekday<br />

<strong>and</strong> on weekend. This shows that, these streets have great importance as being a<br />

spine in the area. This feature, which hadn’t been determined in the spatial integration<br />

analyses, is a sufficient reason to make significant design decisions to link<br />

Istiklal Street <strong>and</strong> Karakoy Square efficiently.

6. <strong>Design</strong> Approaches towards a Spatial Regeneration Process <strong>and</strong> Evaluation<br />

6.1. The Application of Space Syntax on the <strong>Design</strong> Proposal<br />

Analysis of the pedestrian route system through the Galata larger area highlighted an<br />

imbalance between the northern <strong>and</strong> southern parts of Galata. The different aspects of<br />

the Space Syntax analyses of the existing structure have shown that the historical Galata<br />

is not working together with Karakoy <strong>and</strong> Beyoglu districts. The following strategic <strong>and</strong><br />

spatial problems have been identified with regard to the historical core:<br />

• The historical Galata is metrically close to the current live center of Istanbul, but it<br />

is isolated in terms of spatial configuration.<br />

• None of the major streams of movement penetrate into the historical core,<br />

• The historical core is visible but not accessible from the active parts of the town,<br />

• The visual <strong>and</strong> physical linkages between the Galata historic area <strong>and</strong> the neighboring<br />

areas, especially the entrance on the Karakoy ports, are very poor,<br />

• There is no major attraction to the northern end of the historical Galata to provide<br />

destination <strong>for</strong> people from either the retail-led live strip (Istiklal Street) or the<br />

Karakoy ports <strong>and</strong> the parks at the seaside.<br />

• In the vehicular roads around the historical Galata, pedestrian crossings have been<br />

poorly located <strong>and</strong> designed,<br />

• There is a high rate of vacancy inside the historical core. In addition, the retail<br />

activity (or other activity) is not active inside the Historical Galata.<br />

6.2. Assessment of <strong>Design</strong> Proposals<br />

One of the key merits of “Space Syntax” analyses is its ability to analyze design proposals<br />

<strong>and</strong> objectively assess them by measuring the likely effects of spatial changes on social,<br />

economic <strong>and</strong> environmental activity.<br />

A strategic design framework has been developed <strong>for</strong> the historic Galata, old core of<br />

Istanbul, which includes ideas <strong>for</strong> each of the two pedestrian axes of development but<br />

focuses principally on the key problematic points listed above.<br />

In this section some of the Space Syntax design proposals are analyzed <strong>and</strong> compared<br />

with the existing situation in Galata. Space Syntax measures of “spatial integration” are<br />

used to measure the degree of change that our proposal creates in different scales (Figures<br />

284-287). The changes have been described in terms of percentage gains when compared<br />

to existing measures of spatial integration. These percentages signify gains in “pedestrian<br />

movement potentials”.<br />

Four design ideas have been chosen <strong>for</strong> this study; 1) creation of a new link between<br />

Galata <strong>and</strong> Karakoy ports, 2) trans<strong>for</strong>mation of the Hendek street <strong>and</strong> connecting it to the<br />

western border of the area, namely to the Kasimpasa district, 3) opening up the eastern<br />

end of the Hendek street <strong>and</strong> linking it to the Yuksek Kaldirim street which also enables<br />

the connection to the Karakoy, <strong>and</strong> 4) creation of a new link on the northern side <strong>and</strong><br />

between Sishane Square <strong>and</strong> Istiklal Street through Tunel Square.<br />

The results of the syntactic analyses suggest that, four of these design ideas complement<br />

each other <strong>and</strong> need to be implemented in t<strong>and</strong>em.

7. Conclusion: Final Decisions on the Regeneration, Trans<strong>for</strong>mation <strong>and</strong> <strong>Design</strong><br />

Framework <strong>for</strong> Galata District<br />

Space syntax has evolved a spatial redevelopment plan <strong>for</strong> Galata’s historical core which<br />

aims to create a larger <strong>and</strong> unified live center by improving physical connections between<br />

the two important parts of Istanbul’s town center. It uses the spatial potentials of each<br />

area to positively influence the rest of the town center. This strategic plan is based on the<br />

following principles under these headings;<br />

• Transportation<br />

• L<strong>and</strong>-use <strong>and</strong> trans<strong>for</strong>mation<br />

• Significant design solutions<br />

By achieving these principles a larger “live center” is created <strong>for</strong> Galata, which incorporates<br />

all major zones of activity. The historic core becomes an integrated part of<br />

this new live center, with a better chance of being used, enhanced <strong>and</strong> regenerated. A<br />

well-used, safe <strong>and</strong> pleasant historic core would not only create an essential attraction <strong>for</strong><br />

the whole of the city center, but also enhances the social <strong>and</strong> economic status of the town<br />

as a whole.<br />

7.1. Transportation<br />

Transport connections within the Galata area have been analyzed in terms of the likely<br />

effect they will have on pedestrian activity patterns. Thus the two pedestrian axes are<br />

created; one connecting Galata tower to the underground station <strong>and</strong> to the Kasimpasa<br />

mix-uses zone (Hendek Street); the other connecting Istiklal Street - the commercial strip<br />

to the Karakoy square <strong>and</strong> to the ports (Galip Dede <strong>and</strong> Yuksek Kaldirim Streets). Yuksek<br />

Kaldirim Street is proposed to be pedestrian. The Galata Square with its tower is in<br />

the intersection point of these two pedestrian main axes. The extension of the Hendek<br />

pedestrian street creates a link between Galata tower <strong>and</strong> the Kasimpasa zone of mixed<br />

activities.<br />

To ensure the sufficient number of pedestrians <strong>for</strong> the ’live’ historical core, the transportation<br />

facilities below are created;<br />

The area can easily be accessed by all means of transport.<br />

The various public transport nodes are well connected to each other <strong>and</strong> to the Galata<br />

area as a whole.<br />

The transport roads <strong>and</strong> the car parks are located around Galata in a balanced manner.<br />

7.2. L<strong>and</strong>-use <strong>and</strong> trans<strong>for</strong>mation<br />

The spatial configuration <strong>and</strong> l<strong>and</strong> uses of the proposed scheme work h<strong>and</strong> in h<strong>and</strong> to<br />

create a locally distinctive but globally integrated <strong>and</strong> accessible development, with consequent<br />

social <strong>and</strong> economic benefits. The distribution of l<strong>and</strong>-uses within the site addresses<br />

the anticipated activity patterns derived from the model, so that pedestrian-sensitive,<br />

’live’ uses (such as retail, catering <strong>and</strong> local services) line the most accessible routes. The<br />

Hendek Street with a higher potential to attract pedestrian movement is lined with “live”<br />

uses <strong>for</strong> the most parts, which works well with its spatial role. This l<strong>and</strong>-use distribution is<br />

beneficial <strong>for</strong> those occupying the ground floor units <strong>and</strong> <strong>for</strong> pedestrians passing through


576 A. S. Kubat, Ö. Ertekin, E. Eyüboglu, Ö. Özer.<br />

<strong>and</strong> using the area. On the other h<strong>and</strong> residential uses are located in the upper levels of<br />

the buildings or in the areas with lower integration values <strong>and</strong>, there<strong>for</strong>e, lower potentials<br />

to attract through movement. Following this same strategy, the proposed “special development<br />

project zones” <strong>and</strong> the mix l<strong>and</strong>-use zones are located in the close neighboring of<br />

the Galata core, to support <strong>and</strong> utilize the anticipated high levels of activity there.<br />

The waterfront area is trans<strong>for</strong>med into a pedestrian-friendly, well used urban space<br />

enriched with green areas, cultural activities, <strong>and</strong> linked with the Galata Port Project on<br />

the east <strong>and</strong> Persembe Pazari project on the east of the seaside zone. It is also proposed<br />

to create visual <strong>and</strong> physical pedestrian links in between the seaside <strong>and</strong> the core of<br />

the Galata. Enhancing the north-south links between the Galata core <strong>and</strong> the seaside<br />

development area as well as enhancing the existing link from Galata to the commercial<br />

strip namely Istiklal Street will be essential as this enhancement <strong>and</strong> will also encourage<br />

people using the ports to enter <strong>and</strong> navigate the historical core.<br />

7.3. Significant design solutions<br />

7.3.1. A bridge from Tunel to Sishane<br />

The existing bridge connection from Tunel Square to historical Municipality building can<br />

be used as an entrance to the Sishane Square. This can be created by converting <strong>and</strong><br />

redesigning the old Municipality building to socio-cultural activity. This can be another<br />

alternative <strong>for</strong> the high pedestrian flows of Istiklal Street to reach the Hendek Street.<br />

7.3.2. A proposal <strong>for</strong> the link between Galata Square <strong>and</strong> Yuksek Kaldirim Street, opening<br />

a window from Galata to Karakoy<br />

An important new link from Hendek Street to the Yuksek Kaldirim Street is created<br />

despite of their height differences. This new link aims to construct an internal spine <strong>for</strong><br />

the Galata core area <strong>and</strong> reintegrate it to the existing center of activity. The alignment<br />

of the new link with the Galata Square enables it to benefit from the existing high levels<br />

of pedestrian movements there. The development of this new link however, has to be<br />

accompanied by the development of a new cultural, social, tourism, <strong>and</strong> leisure activity<br />

zone in order to create an attraction “pole” at this location. The pedestrianised Yuksek<br />

Kaldirim street <strong>and</strong> the Karakoy port in its extension is a potential which will provide<br />

the main pedestrian flow of such a destination.<br />

The central element of the design proposals is the extension of the Hendek Street,<br />

both to the north <strong>and</strong> south, to create a new pedestrian route between Kasimpasa zone<br />

to the Yuksek Kaldirim Street. The creation of this link involves a number of careful<br />

physical trans<strong>for</strong>mations, which require further analysis. These changes, however, are close<br />

to “conservative surgery” of the historical core than radical trans<strong>for</strong>mation of the urban<br />

fabric. The idea here is to gain maximum benefit from a minimal change.<br />

The optimal alignment of Hendek Street has been established <strong>and</strong> tested using the<br />

findings of Space Syntax study. This alignment creates a direct line of sight <strong>and</strong> access<br />

from Hendek Street to the Yuksek Kaldirim Street (Figure 288). The Kasimpasa zone, the<br />

underground station, Yuksek Kaldirim <strong>and</strong> the ports are all connected by this alignment.<br />

A considerable design approach is proposed by opening up the ground floor of the<br />

building/s or the urban fabric <strong>and</strong> trans<strong>for</strong>ming it to a public passageway (Figure ??).<br />

This design appears in principal to resolve the problem of access without damaging the<br />

structure or the facade of the listed buildings. Further architectural work is required <strong>for</strong>

Yuksek Kaldirim Street. An elevator or ramps on the intersection of these two streets<br />

(namely Hendek <strong>and</strong> Yuksek Kaldirim) can be proposed.<br />

7.3.3. <strong>Design</strong> of the Galata Square as a major public square<br />

The main public space of Galata; with its tower which is the apex of the Genoese <strong>for</strong>tification<br />

of medieval Galata, is located at one end of the Hendek street, responds to the<br />

previously discussed issue of pedestrian orientation <strong>and</strong> navigation by integrating this<br />

space within the network of key public spaces.<br />

It is known that, the quality of the public spaces <strong>and</strong> squares reflect the success of<br />

the urban centers. The degree, to which spaces are both well used <strong>and</strong> pleasant, is largely<br />

influenced by their location within the pedestrian movement network.<br />

7.3.4. Gates <strong>for</strong> Galata<br />

Attractive gates are proposed to create the accessibility <strong>for</strong> the site.<br />

Gate1, is <strong>for</strong> the pedestrians entering historical Galata from Metro stations <strong>and</strong> Sishane<br />

Square which is on the axis of Hendek Street <strong>and</strong> gives a visual contact with Galata Tower.<br />

Gate 2, is the entrance from Tunel Square which is the end of Istiklal Street.<br />

Gate 3, is especially <strong>for</strong> the pedestrians using Karakoy Square.<br />

Gate 4, is <strong>for</strong> the people approaching to Galata by sea ways.<br />

8. Concluding Remarks<br />

Galata is at a very important stage in its historic development. Besides the historical<br />

l<strong>and</strong>scape, which should be preserved, various number <strong>and</strong> scale of development projects<br />

such as ’Galata Dock Project’ <strong>and</strong> ’urban design projects <strong>for</strong> the waterfront area’ or<br />

other large-scale ’development projects’, should be encouraged <strong>for</strong> its successful social<br />

<strong>and</strong> economic per<strong>for</strong>mance.

The critical economic mass of leisure <strong>and</strong> retailing must be brought together in a<br />

way as to generate parallel social gains, thus Galata as a part of Istanbul’s city center<br />

<strong>and</strong> is not just retail <strong>and</strong> touristy market, but also a place of social <strong>and</strong> civic importance.<br />

Galata requires a carefully planned framework of public spaces <strong>and</strong> pedestrian connections,<br />

together <strong>for</strong>ming the public realm of the historical center of Istanbul. If this essential<br />

infrastructure is not provided new developments it will risk turning their backs on each<br />

other <strong>and</strong> acting as st<strong>and</strong>-alone facilities. To h<strong>and</strong>le the strategy properly, the synergy<br />

between individual projects is created, <strong>and</strong> people are allowed to flow easily between<br />

them. In other words, to h<strong>and</strong>le public realm properly, rich pedestrian connections are<br />

created in Galata, more inter-accessibility is allowed <strong>and</strong> thus the risk of social stagnation<br />

is removed.<br />

In conclusion, we are convinced from our analyses that Galata has much significant<br />

potential to be sensitively developed as a place that is people-focused, connected, inclusive<br />

<strong>and</strong> integrated, <strong>and</strong> that can radically enhance the social, economic <strong>and</strong> environmental<br />

quality of the wider Istanbul metropolitan area. This can be achieved through a coordinated<br />

implementation of an agreed planning policy, based on an integrated spatial master<br />

plan, the basis of which outlined briefly in this paper.<br />
