Gyaros

Gyaros (Greek: Γυάρος pronounced [ˈʝaros]), also locally known as Gioura (Greek: Γιούρα), is an arid and uninhabited Greek island in the northern Cyclades near the islands of Andros and Tinos, with an area of 23 square kilometres (9 sq mi). It is a part of the municipality of Ano Syros, which lies primarily on the island of Syros. This and other small islands of the Aegean Sea served as places of exile for important people in the early Roman Empire. The extremity of its desolation was proverbial among Roman authors, such as Tacitus and Juvenal. The island operated as a prison island and concentration camp for left-wing political dissidents in Greece from 1948 until 1974. During that time, at least 22,000 people were exiled or imprisoned on the island. It is an island of great ecological importance as it hosts the largest population of monk seals in the Mediterranean.
