Kythera is located south of Greece, at the crossroads of three seas (Aegean Sea, Ionian Sea and Cretan Sea). In other terms, it is located between Peloponnese and Crete. From an administrative point of view the island belongs to the region of Attica (county of Piraeus) but historically speaking it is part of the Eptanissa (the seven islands of the Ionian Sea). Kythera is a municipal corporation that includes 13 geographical counties covering an area of 284 km². The 13 counties are administratively represented by local councils. Kythera’s population is approximately 4,000.
From a geographical point of view Kythera is part of the Alpine chain, specifically the southern branch of the Tethysian system that extends from the Dinaric Alps to the Taurus Mountains in Syria. Simply put, Kythera is a major gateway to the Aegean Sea from the central and western Mediterranean Sea.
The coastline of Kythera is approximately 90 km long (49 Nm). It is at 80 km (43 Nm) from Crete, 21 km (12 Nm) from Neapoli and 200 km (108 Nm) from Piraeus. The geographical coordinates of Kythera are 36.8° latitude north and 22.6° longitude east.
