Oinousses is a cluster of nine small islands and islets, namely Oinoussa, Panagia, Vatos, Gaidouronissi, Pontikonisso, Archontonisso, Pontikoudiko, Laimoudiko and Prassonisia.
When the Greek Revolution began, an island called Psara offered up its entire commercial fleet - the third largest in Greece after those of Hydra and Spetses - to the struggle for liberation.
