Cythera (Greek: Κύθηρα, also transliterated Kythera, Kythira, Kithira. The Italian Cerigo can be used in speaking of late medival and early modern Cythera. ) 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 (although at large distance from Attica itself), 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. 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, Venetian, Ottoman and British civilisations as well as its numerous visitors.
