Zakynthos or Zante is a Greek island in the Ionian Sea. It is the third largest of the Ionian Islands. Zakynthos is a separate regional unit of the Ionian Islands region, and its only municipality. It covers an area of 405.55 km² (156.6 sq mi) and its coastline is roughly 123 km (76 mi) in length. The name, like all similar names ending in -nthos, is pre-Mycenaean or Pelasgian in origin. In Greek mythology the island was said to be named after Zakynthos, the son of the legendary Arcadian chief Dardanus.
