Zindan Hill, which is known to have been used as the Courthouse in the Byzantine period in ancient times and consists of high rocks, is located in Ortahisar Town. There are caves carved from rock and pits resembling cemeteries.

It is located 1 km from the center of Ortahisar Town. The dungeon hill was discovered by chance while a cleaning effort was being carried out in the area. It appears that the structure was built as a complex building. When the ruins that have survived until today are examined, there is a guard station at the entrance, an interrogation cell next to it, a prisoner's cell on the upper level and a trial hall next to it.
