The earliest name of Kemerhisar was Tuwanuwa. It was an important Hittite city on the way to Cilician Gates in Toros Mountains. During the Hellenistic age, the name was Tyana. It was briefly the capital of Cappadocia, the vassal of Roman Empire. Apollonius of Tyana, a contemporary of Christ, was born in Tyana. The town was an important settlement during Roman Empire domination and the aqueduct, which is the symbol of the town, had been constructed by the emperors Trajan and Hadrian. After the town was incorporated into the Seljuk Empire in the 11th century, the Turks called the city Kilisehisar (Churchfort). The name was later replaced by the name Kemerhisar (Vaultfort), referring to the historical Roman aqueduct within the town.
