Kythera, is an island in Greece, once part of the Ionian Islands. It lies opposite the south-eastern tip of the Peloponnese peninsula. It is administratively part of the Islands regional unit, which is part of the Attica region, Greece.
For many centuries, while naval travel was the only means for transportation, the island possessed a strategic location. Since ancient times, until the mid 19th century, Kythira had been a crossroads of merchants, sailors, and conquerors. As such, it has had a long and varied history and has been influenced by many civilisations and cultures.
