Château d'If

Château d'If is a small fortress on the island of If in the Bay of Marseille, roughly 3.5 km offshore from the Vieux-Port in the Provence-Alpes-Côte d'Azur region of France. François I ordered its construction from 1524 to defend the approaches to the port, and it later served for centuries as a state prison, holding Protestants, political detainees and common prisoners. Its worldwide fame comes from Alexandre Dumas's novel The Count of Monte Cristo, whose hero Edmond Dantès is jailed here, and visitors still look for the cell associated with the fictional prisoner. The visit begins with a short walk up from the landing stage to the square fortress, whose thick walls, three towers and inner courtyard are easy to take in on a self-guided circuit. Inside, visitors can enter the cells, some with surviving graffiti, climb to the ramparts and look across the bay to the Frioul islands, the Corniche and the city skyline with Notre-Dame de la Garde on its hill. The boat leaves from the Quai des Belges at the Vieux-Port and takes about 20 minutes each way; the crossing itself gives a good photographic angle on the harbour entrance and the fort's silhouette as it approaches. A typical visit takes two and a half to three hours including the crossing, and the island has little shade or shelter, so sun protection and water are useful in summer. The best vantage points are the rampart terraces on the seaward side, which give wide views toward the open Mediterranean, and the roof terraces facing Marseille. Crowds are heaviest in July and August around late morning, when boats fill quickly and the courtyard becomes busy; early departures and shoulder-season weekdays are much calmer. Crossings can be cancelled or delayed in strong mistral wind, so the day's service should be checked in advance. The site is run as a national monument, and entry costs about EUR 7, with the boat fare charged separately by the operator of the Frioul-If service.
