At the northern end of Kızkalesi beach, Corycus Castle was either built or rebuilt by the Byzantines, briefly occupied by the Armenian kingdom of Cilicia and once connected to Kızkalesi by a causeway. Walk carefully up the worn stairway to the east, where a ruined tower affords a fine view of Kızkalesi Castle.
Across the highway is a necropolis , once the burial ground for tradespeople. Tombs and rock carvings include a 5th-century relief of a warrior with a raised sword.
