Access the forts and islets

Saint-Malo, the city of privateers, is protected by extraordinary maritime fortifications designed by Vauban at the end of the 17th century. It’s only a short step from romantic Brittany and its medieval fortresses. We invite you to dive in and discover some of the finest masterpieces of human genius.

Vauban and maritime fortifications

Advanced posts are numerous around Saint-Malo. In order to defend the kingdom from English and Dutch invasions, Louis XIV entrusted Vauban with the protection of the French coast. But the man who carried out the work was none other than Garangeau, appointed by Vauban as “chief engineer and director of the fortifications of Saint-Malo”. The citadels built on rocks in the middle of the sea bear witness to the military genius of the Sun King’s engineers.

In order to protect the town, the Bay of Saint-Malo was fortified as early as the 17th century. Based on plans by Vauban (King Louis XIV’s chief architect), Garangeau built the 4 forts on the offshore islets, making the harbour entrances impregnable.

The Fort National, at the foot of the ramparts

The Fort National, known as the Fort Royal in the time of Louis XIV, stands on the Islet rock. Built in 1689 by Garangeau to Vauban’s plans, it protected the ramparts of the corsair town. You can reach it on foot at low tide.

If you see the French flag hoisted over the fort, that means the site is open to visitors!

The Petit-Bé fort

More confidential, the Petit-Bé fort, nestling behind the Grand-Bé island was completed in 1707, on the death of Vauban. It has now been restored by a private individual with a passion for maritime fortifications. It can be reached on foot or by ferry boat, depending on the tide. You need to be careful, and find out what time the tide is out for the day before setting off. To do this, take the reference time and calculate 1? hours before and 1? hours after. This will give you your access window. Visits are possible all year round.

Le fort de la Conchée, off Saint-Malo

Further out, four kilometres from the shore, facing the large Rochebonne beach, is the fort de la Conchée. This ship’s fort, 65 metres long and 32 metres wide, had a garrison of 200 men. Since 1989, it has belonged to the Compagnie du Fort de la Conchée association, which has already restored more than 80% of the building. Given the difficulties of access, the fort is only open to the public two days a year for the Heritage Days. Alternatively, take advantage of a virtual tour of the Fort de la Conchée offered on the monument’s website.

The Association of Friends of the Fort de la Conchée, offers tours during major events, including the European Heritage Days.

When the tide matters! The Grand Bé islet

Le Grand Bé, Chateaubriand’s final resting place

Le Grand Bé is an uninhabited islet located a few hundred metres off the ramparts of Saint-Malo. It is here, facing the sea, that the illustrious Romantic writer François-René de Chateaubriand is buried. The site also provides an incredible panorama of the corsair city.

To reach the Grand Bé you need to pay attention to the tides. You can only get there for a few hours a day, at low tide, by crossing Bon Secours beach. To be on the safe side, you need to refer to the low tide time of the day and add 1? hours before and after this reference time. This gives you an access window of 3 hours.
