Oinousses (Greek: Οινούσσες, alternative forms: Aignousa (Αιγνούσα) or Egnousa (Εγνούσα)) is a barren cluster of 1 larger and 8 smaller islands some 2 kilometres (1 mile) off the north-east coast of the Greek island of Chios and 8 km (5 miles) west of Turkey. Administratively the islands form a municipality within the Chios regional unit, which is part of the North Aegean region. The principal town of the islands and seat of the municipality is also called Oinousses. Oinousses has a small resident population, living primarily in the island's town of Oinoússes (pop. 792), and a recently built monastery. The town is centred on a square and a small port; it includes a school, several churches, a Naval high school and a maritime museum. The only other populated settlements are Kástron (pop. 29) and Aspalathrókampos (5). [Source Wikipedia]
