From prison to paradise: Once a dreaded prison island, this remote haven in Greece is now protecting one of the world's rarest seals

Gyaros, a remote Greek island in the Cyclades, was once used for political imprisonment but now protects the endangered Mediterranean monk seal.

The island's uninhabited status and tightly managed human activity allow monk seals to rest, reproduce, and nurse their young along its coastline.

Gyaros' transformation from a feared prison island to a protected marine sanctuary highlights a convergence of human history and ecological recovery.
