Gorgona

Gorgona is the northernmost island in the Tuscan Archipelago, a group of islands off the west coast of Italy. Between Corsica and Livorno, this diminutive island has been valued most for its wildlife, especially marine birds, and its isolation. The latter quality resulted in the foundation of Gorgona Abbey in the Middle Ages. After its closure the monastery grounds and buildings were appropriated in 1869, at the foundation of an agricultural penal colony, which is currently in use.
