Château d’If
Provence-Alpes-Côte d'Azur
The Château d'If is a fortress built between 1524 and 1531 on the Île d'If, the smallest island in the Frioul archipelago off Marseille, France. Originally constructed on the orders of King Francis I to protect the coastline from sea attacks, it later became a notorious prison until the late 19th century. The fortress is a square, three-story building with three towers and large gun embrasures, surrounded by high ramparts. Its isolated location and treacherous surrounding waters made it an escape-proof prison, used mainly for political and religious detainees, including over 3,500 Huguenots. The prison's fame was immortalized by Alexandre Dumas in his 1844 novel The Count of Monte Cristo, where the protagonist Edmond Dantès was imprisoned and made a daring escape. Today, the château is a monument historique and a popular tourist destination accessible by boat from Marseille's Old Port. Visitors can explore the dungeons, ramparts, and enjoy panoramic views of the Mediterranean. The fortress exemplifies the transition from medieval to early modern military architecture and is part of the Calanques National Park since 2012.
