Right: General view of the concentric oval walls of the<br />

Ludus <strong>at</strong> Portus<br />

ran in an east to west direction for some 250 metres and<br />

was composed of a series of parallel corridors running from<br />

north to south for its entire length. Analysis of the façade<br />

th<strong>at</strong> opened on to the channel revealed th<strong>at</strong> the building<br />

underwent major changes during the course of the Imperial<br />

period, culmin<strong>at</strong>ing in the l<strong>at</strong>er fifth century AD, when it was<br />

incorpor<strong>at</strong>ed into the defensive fortific<strong>at</strong>ion (mura<br />

costantiniane) th<strong>at</strong> encircled the port complex as a whole.<br />

Excav<strong>at</strong>ions also confirmed th<strong>at</strong> during the Severan<br />

period the channel was backfilled with sand and then<br />

covered over with a large (42 metres x 35 metres) oval-plan<br />

building. This probably can be identified as a small<br />

amphithe<strong>at</strong>re (ludus). It has important implic<strong>at</strong>ions for our<br />

understanding of the Palazzo Imperiale and adjacent<br />

buildings, given th<strong>at</strong> structures of this kind are often<br />

associ<strong>at</strong>ed with Imperial palaces <strong>at</strong> <strong>Rome</strong>, such as the early<br />

third–century AD Palazzo Sessoriano, and military<br />

complexes, such as the Castra Praetoria.<br />

In addition to this work, <strong>at</strong>tention was also directed<br />

towards further understanding l<strong>at</strong>e Imperial levels, not least<br />

including the excav<strong>at</strong>ion of a series of l<strong>at</strong>e antique burials<br />

outside the mura costantiniane. <strong>The</strong> work on the excav<strong>at</strong>ion was<br />

complemented by a programme of environmental coring by<br />

J.-P. Goiran (Lyon) in an <strong>at</strong>tempt to understand better the<br />

environmental context of the port: six cores of up to ten<br />

metres depth were taken <strong>at</strong> different points across the<br />

excav<strong>at</strong>ion and surrounding area. In addition, samples of the<br />

pine and oak were taken from cladding around the inside of<br />

the Hadrianic cistern for dendrochronological d<strong>at</strong>ing and<br />

sourcing work (carried out by S. Manning, Cornell University).<br />

<strong>The</strong> Trajanic Basin<br />

A team led by Justin Dix (N<strong>at</strong>ional Oceanographic Centre,<br />

Southampton) undertook a sub-bottom sonar survey of the<br />

Trajanic basin in order to reveal the depth and profile of the<br />

basin, and its rel<strong>at</strong>ionship with the Palazzo Imperiale. Initial<br />
