Kythira is an island in Greece lying opposite the south-eastern tip of the Peloponnese peninsula. It is traditionally listed as one of the seven main Ionian Islands, although it is distant from the main group. Administratively, it belongs to the Islands regional unit, which is part of the Attica region, despite its distance from the Saronic Islands, around which the rest of Attica is centered. The island is strategically located between the Greek mainland and Crete, and from ancient times until the mid 19th century was a crossroads of merchants, sailors, and conquerors. As such, it has had a long and varied history and has been influenced by many civilizations and cultures. This is reflected in its architecture (a blend of traditional, Aegean and Venetian elements), as well as the traditions and customs, influenced by centuries of coexistence of the Greek, and Venetian cultures.
Kythira has a land area of 279.593 square kilometres (107.95 sq mi); it is located at the southwestern exit from the Aegean Sea, behind Cape Malea. The rugged terrain is a result of prevailing winds from the surrounding seas which have shaped its shores into steep rocky cliffs with deep bays. The island has many beaches, of various composition and size; only half of them can be reached by road through the mountainous terrain of the island. The Kythirian Straits are nearby.
Kythira is close to the Hellenic arc plate boundary zone, and thus highly prone to earthquakes. Many earthquakes in recorded history have had their epicentres near or on the island. Probably the largest in recent times is the 1903 earthquake near at the village of Mitata, that caused significant damage as well as limited loss of life. It has had two major earthquakes in the 21st century: that of November 5, 2004, measuring between 5.6 and 5.8 on the Richter scale and the earthquake of January 8, 2006, measuring 6.9 on the Richter scale. The epicenter of the latter was in the sea about 20 km (12 mi) to the east of Kythira, with a focus at a depth of approximately 70 km (43 mi). Many buildings were damaged, particularly old ones, mostly in the village of Mitata, but with no loss of life. It was felt as far as Italy, Egypt, Malta and Jordan.
