The way houses are built in this region is in some ways timeless, particularly the roofs. Modern ceilings can show how ancient roofs, which we have to reconstruct from small fragments, were built. While it is easy to look at modern houses in villages near the site, it is more complicated when it concerns the ancient houses.
No roof survives in place at Amara West: only the walls and floors remain. But not everything has disappeared. Impressions on mud, though perhaps unimpressive at first sight are very helpful as they record the different layers and materials used to build the roofs.
The wood and other plant material disappeared long ago, eaten by termites. But the shapes impressed in the mud roofs tell us that large beams and poles were used. The roof of our dig house is built in the same way, though metal beams (sometimes from the abandoned railway line) are now preferred.
Layers of grass, reeds and palm fronds, sometimes tied into bundles, were also widely used, along with two different types of matt, as can be seen in some of the mud impressions. The way in which the mats were woven is very similar to those still made and used today in this area.
Though distant in time and culture, the modern houses can act as a place for us to test our theories and reconstructions of the ancient roofs. Some techniques survived thousands of years of changing cultures in northern Sudan, most probably because they are those which fit best with the climate and materials available in the area.
