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.

The castle is said to have been built by Máel Coluim III of Scotland, after he had razed to the ground the castle in which Macbeth of Scotland according to much later tradition, murdered Máel Coluim"s father Donnchad I of Scotland, and which stood on a hill around 1 km to the north-east.
The first Inverness Castle was partially destroyed by King Robert I of Scotland and a replacement castle was sacked in the 15th century by the Clan Donald during the Siege of Inverness (1429). The castle was occupied during the Raid on Ross in 1491.
In 1548 another castle with tower was completed by George Gordon, 4th Earl of Huntly (1514–1562). He was constable of the castle until 1562.
