Plaka is the capital of Milos and seat of the municipality of Milos, which includes Milos and the nearby rocky islands. According to the 2011 census, it has 749 inhabitants. Plaka got its name from the level ground on which the houses were built when the Castle was no longer sufficient to house the population. It is built at an altitude of 220 meters, overlooking the gulf of Milos. The current settlement was created by the abandonment of the previous one, Zefyria or Chora (for this reason Plaka is not called Chora).
Plaka has a strong traditional color, with Cycladic architecture, narrow cobbled streets and small traditional shops, restaurants and cafes. Car traffic is prohibited within the settlement. At the highest point of Plaka, on a hill of volcanic origin, is the Castle, which was built by the Venetians in the 13th century. At the top of the castle is the Church of the Dormition of the Virgin or Mesa Panagia, while lower down is the Assumption of Christ or Panagia Thalassitra. In Plaka is also the metropolis of Milos, the Holy Church of Genesis Theotokos or Panagia i Korfiatissa. The church was built in 1820 and is of the Byzantine-Cycladic style. Many relics and icons are kept in the church, together with the icon of Panagia Korfiatissa.
The archaeological and folklore museum of Milos is located in Plaka, while most of the island’s public services are housed there.
