The preservation of building remains found at Zeugma this summer has been impressive.
Walls survive in places to heights of several metres, and many mosaic floors have been found intact.
However, sometimes, it is still difficult to imagine how the original buildings may have looked when they stood to their full height. This is often because more than one phase of a building survives, and it is sometimes difficult to separate the original elements of a house from the later additions and alterations. Graphic representations like these, help archaeological specialists and the general public understand the buildings and how they have evolved. Although only the lower parts of walls survive, it is often possible to make informed estimations of the overall form of the structure based upon the fragmentary remains. For example, by measuring the diameter of a column drum, it is relatively easy to make an estimate of the original column height - classical architecture tends to follow a set of strictly applied rules.
