Abstract People have some kind of internal model of a geographical space. This research is concerned with aspects of environmental cognition; that is our ability to imagine about our spatial world. In particular, this study makes an attempt to describe cognitive maps and the individual differences between people's map. Data was gathered from a sample of fifty persons. All of them walked through a historical region in Isfahan and were asked to draw a sketch map; the map was then assessed. The major finding was that our spatial knowledge is “map-like” rather than, say, a sequence of instructions for various routes.
