A map of cracksappeared due to movements in the foundation and walls. Presently the church is stable;however previous movement has left some scars.The first step was measuring and surveying the actual state of the church then the followinginterventions took place:• To guarantee the stability of the mural paintings during the reparation of the vault, atemporary protective covering was placed over the paintings.• To reinforce the vault during the restoration process, a support system was placedconsisting of three rows of seven braces which made a total of 21 braces thatsupported wood planks.• After the roof structure was removed and the dirt was cleaned away, we started toapply the fibre reinforced system. Two windows that were buried under inertmaterial were discovered.• Reinforcing the outside of the vault produced a self supporting body which retainedthe weight of ashlars in the case of movement; also by working on the exterior of thevault, you avoid touching any mural paintings found on the interior which was thecase here.37º <strong>IAHS</strong> <strong>World</strong> <strong>Congress</strong> On Housing Science 341
