Aptera was an ancient city, now an archaeological site in Kalives [4]in western Crete, a kilometre inland from the southern shore of Souda Bay, about 13 km east of the city of Chania in the municipality of Chania.

In Greek mythology, Aptera was the site of the legendary contest between the Sirens and the Muses, when after the victory of the Muses, the Sirens lost the feathers of their wings from their shoulders, and having thus become white, cast themselves into the sea. The name of the city literally means "without wings", and the neighbouring islands Leucae means "white".

It was destroyed by earthquake during the 7th century. By the 12th century, a monastery of St. John Theologos had been built on the site; it continued in operation until 1964. The site is now maintained by the Greek Ministry of Culture, Department of Antiquities.[11] The hilltop, about 150 metres above the sea, commands views of Souda Bay and the Akrotiri Peninsula to the north, the Lefka Ori (White Mountains) to the south, and Kalives and the Turkish Izzedin Fortress to the east; the city of Chania is not quite visible to the west.
