The village's 3 km long beach is on the Keros Gulf.

The gulf is east of the village and was an important port until the late Middle Ages.

According to local folklore, the first settler was Kalliopi or Kalli, a rich resident of Hephaistia, who was expelled due to improper conduct.

The settlement was formerly closer to the sea, near the present locality Ariones.

The naval general Georgios Kapetanakis, active in the Greek War of Independence, came from Kalliopi.
