A short video documentary built around a computer simulation of medieval Cairo. It begins with “fly-overs” and ” walk-throughs” of the city in its twelfth-century incarnation as a royal compound. The video then traces the spatial development and morphological transformation of the historic core of Cairo up to the sixteenth century. Computer visualization technology, which has been used primarily by the entertainment industry, is now making it possible to tell the urban history of Cairo and view its growth and evolution.
