Derbent Fortress

The Citadel, Ancient City and Fortress Buildings of Derbent were part of the northern lines of the Sasanian Persian Empire, which extended east and west of the Caspian Sea. The fortification was built in stone. It consisted of two parallel walls that formed a barrier from the seashore up to the mountain. The town of Derbent was built between these two walls, and has retained part of its medieval fabric. The site continued to be of great strategic importance until the 19th century.
