The ancient Kahta Castle in Türkiye’s southeastern Adiyaman province dating back to the Commagene period has opened its doors to visitors after 17 years. Built by the Commagene civilization, Kahta Castle fascinates visitors with its bazaar, mosque, dungeon, and waterways. Bearing traces of three important civilizations on the route to Mount Nemrut, the castle was closed to visitors in 2005 for security reasons. The restoration work in the castle has been completed in three stages. ECI reports, citing Anadolu agency.
