Two main straight roads cross the land of the city. Bishapur has 4 gates each on the end of the mentioned roads. The west gate is the main entrance of the city. Like every other town, it consists of two parts. First, the royal or governmental area and an area for citizens’ residence. The latter part contains common civil facilities as houses, Bazaar, caravansary, bath house and etc. The royal part includes a palace, a royal hall, the mosaic loggia, two monumental columns and the magnificent Anahita Temple. As a matter of fact the main material used in construction of Bishapur is stone. In the past, the city was guarded by a moat around it. As well as every other city, they built it near a river to provide water supply.
