To support these studies, there are strong needs for a tool to share specialists' knowledge as well as to perform systematic inference. It is an objective of this paper to discuss a knowledge system the authors developed to support spatial analysis of excavated ruins. Taking an analysis on a plan of Islamic houses in Tunis as the case, the authors showed that computerized knowledge system that works with a high speed personal computer could support such work as described above.
