Kemerhisar is a town (belde) in the Bor District, Niğde Province, Turkey.

It was an important Hitite city on the way to Cilician Gates in Toros Mountains.

[4] The town was an important settlement during Roman Empire domination and the 1.5 kilometres (0.93 mi) aqueduct, which is the symbol of the town, had been constructed by the emperors Trajan and Hadrian.

[5] 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.
