Gor (Firuzabad) is a great Circular City built by the founder of the Sassanian dynasty, King Ardashir 1. Huge clay double ramparts forming a perfect circle surrounded the city. In it were four main gates from which led the main thoroughfares dividing the city into four equal sections. Where they crossed at the center there was a square tower called a minar, either a political symbol of the king's power and authority or a religious building at the summit of which a sacred fire burned.
