The inner town is situated on a high terrace in the foot of the Zabuite hill. It is spread on a territory of a quarter of a square kilometer approximately in the middle of the Military fortification. It has an irregular Г- form plan in view of the extension on the north and the so called turn that was formed in the north. The southern, eastern and northern way of the wall were found at this stage of research. The foundation is 3.20 m.wide. They were 10 m.high, made of large limestone squares where in the extension on the north the wall’s inner part was made of  quarry rocks soldered with white plaster. The wall was 2.80 m. thick. Rectangular towers the so called bastions were also built on the northern and eastern wall of the extension for better defense. The most well preserved up to 10 m. sections of the fortress walls are also here. The length of the southern fortress wall is 148 m., of the eastern wall- 701 m. and of the northern wall- 558 m.

The round towers connected the fortification’s corners. They are with an outer diameter of 9 m. Three gates were found, southern, eastern and northern one respectively raising at 15 m.height. The three gates have a similar plan- two paralleling pairs, almost square rooms, making the passage. In the height of the passage there is an over gate overarching tower that unites them. There is a winding stairs in one of the rooms and in the southern one it is from the east. The entrance was closed by a double wooden door and a metal one dropping on grains the so called cataract whose dropping mechanism was on the third floor. The northern gate also called iron or main one was an exception because it was supplied with an additional second cataract. the massive wooden door was inside the gate and respectively opened inwards. The wall ended with pinnacles forming loop- holes. The fortress’ s defenders used to fire on the enemy’ s soldiers from the vault’s shafts.
