Irakleia or Heraklia is an island and a former community in the Cyclades, Greece. It is a small island between the islands of Naxos and Ios. In close proximity to Schoinoussa, Koufonisi, Donoussa, and Keros islands, together they form the Small Cyclades. The port is called Agios Georgios, while the “capital”/chora on the top of the island is called Panagia (Madonna).
The biggest caves in the Cyclades are located on Irakleia.
