South Stoa I. Detail showing a wall of sub-dried mudbrick on top of a stone socle (lowest course of the wall). This type of construction was very common in the ancient world. If kept dry (by a coating of plaster) and protected from the rain (by a roof), the mudbrick makes an economical yet very strong building material for walls. When a building collapses and mudbrick is exposed to water, the mubbrick begins to disintegrate and "melt". This is one the ways in which buildings become buried and archaeological sites are formed!
