Silvan Castle

There is no reliable data about when the Silvan Castle was built, but it has been thought that it could have been built in 77 BC when Silvan was founded as the capital city of Tigranes. During the Byzantine, Hamdanid, and Marwanid periods, it was repaired and bastions were added. It has 50 bastions and nine gates. It is now one of the city's most visited attractions.
