Near the village of Kocahisar (Eski Kahta), Yeni Kale was constructed by the Commagenes and used alongside Arsameia, opposite. The castle, which was restored by the Romans and then the Mamluks, had its most recent renovations in the 1970s. Within the site are a bazaar, mosque, dungeon, aqueducts, dovecote ruins and various inscriptions. The aqueduct, which descends from the castle to Nymphois, is connected to Arsameia via a tunnel, with water reachable via this 80m route.
