Petit Bé is a tidal island near Saint-Malo, France, close to the larger island of Grand Bé. There is a fort built in the 17th century. It was part of the defense belt designed by Vauban to protect the city of Saint-Malo from British and Dutch fleets. This belt also included the walls of the Saint Malo, Fort National, Fort Harbour, Fort de la Conchée, and the forts of Cézembre and Pointe de la Varde; these last two have been destroyed. The forts were built by the Saint-Malo engineer Siméon Garangeau.
The fort belonged to the French army until 1885. Later, the army turned the fort over to the city of Saint-Malo. It became a Monument historique in 1921, but was neglected until 2000, when the city gave a free rent to a non-profit organization for the renovation and visiting. At low tide the island can be reached on foot from the nearby Bon-Secours beach.
References:The Château du Lude is one of the many great châteaux of the Loire Valley in France. Le Lude is the most northerly château of the Loire Valley and one of the last important historic castles in France, still inhabited by the same family for the last 260 years. The château is testimony to four centuries of French architecture, as a stronghold transformed into an elegant house during the Renaissance and the 18th century. The monument is located in the valley of Le Loir. Its gardens have evolved throughout the centuries.
