Fortress Walls

The fortress walls were built of hewn limestone. These walls were resistant even to the most modern weapons by being very thick and durable. After the last restoration, 25 semi-circle and one square-shaped tower-type bulwark (donjon), and approximately 500 m of the fortress fence with a total length of 1500 m remained stable. Its current thickness varies between 3-3.5m and height between 10-12m. People used to call the Rectangle tower defense system jabbakhan (weapon warehouse). This fortress was used as a weapon warehouse in the Middle Ages and later. The main purpose of its construction was to keep the area under adequate control and use it as a weapon warehouse to further strengthen the defense of the northern part of Baku.
