Kaya Bey Kyo - by the Ottoman authorities - literally translated "The Village of the Stone Master".

Like most villages in the area, the elderly population before the migration of Balkanis belongs to the Gagauz ethnographic group.

[1] The population of the village consists entirely of ethnic Bulgarians, descendants of settlers from the Balkan Mountains (Kotel and Elena regions) and Southern Romania.

A compact group of ethnic Bulgarians, who previously inhabited Northern Dobruja, settled in Kamen Bryag as a result of the Treaty of Craiova.

2 km south of the village is the archeological site "Yailata" with numerous tombs, stone dwellings and an early Byzantine fortress wall.
