Îles du Frioul

The Frioul archipelago is a group of 4 islands located off the Mediterranean coast of France, approximately at 4 kilometres (2 miles) from Marseille. The Château d'If is a fortress (later a prison) located on the island of If, the smallest island in the archipelago. Access to the island is strictly regulated and only a few providers are authorized. The flight by drone over the islands is not allowed (except few areas), but shooting from above the sea is.
