Uçhisar is first mentioned in a 14th-century chronicle by Aziz ibn Ardasir. The general area had been occupied much earlier, however. The Hittites may have used the natural structures of the cliffs as refuges and strongholds against possible attacks. In the seventh century AD, the Byzantines created a 'buffer zone' in the area against Islamic expansion. The nature of the terrain was conducive to defence, while the camouflage of the buildings provided an improved defence against attackers.
