Othonoi (Greek: Οθωνοί, Italian: Fanò) is an island and a former community of the Ionian Islands, Greece. Since the 2011 local government reform it is part of the municipality of Corfu, of which it is a municipal unit. It is the westernmost point of Greece, located northwest of Corfu. Population 392 (2011). It is the biggest of the Diapontia Islands. In the 19th century the island used to be the capital of the Diapontia Islands municipality, which also included nearby islands of Ereikoussa, Mathraki islets and rocks of Diakopo, Diaplo, Karavi, Kastrino, Leipso, Ostrako, Plaka, Plateia and Tracheia.
Othoni is about 47 nautical miles from Santa Maria di Leuca cape, Italy. According to a legend, in the ancient times it was the island of nymph Calypso who lived in a large cave. Odysseus fell in love and remained like a prisoner there for seven years. Homer called thιs island Ogygia. In the Odyssey one reads that there was a strong scent of cypress on this island. Othonoi is a place with many of these trees and on a hot day one may smell their resin.
Odysseus left Ogygia by raft, which sank at Scheria on the island of Corfu. This is an extra element that justifies the legend of Othonoi being Ogygia, because of the short distance that separates the two islands. Most beaches on the island are accessible by boat, including Ammos, Molos, Kamini, Kanoula, Kontoskes, Rogi, Fyki, Xilosermi, and Aspri Ammos (photo). It is a well known island for underwater photography because of the peculiar geomorphology of the seabed and the many caves. Othoni was frequently visited by the French naturalist Jacques Cousteau and his exploratory vessel Calypso.
