In 1692 the naval Battle of La Hougue took place between the English and the French close to the island of Tatihou. The so-called Vauban Tower (Tour Vauban de Tatihou) was built in 1694. In 1756 the surroundings of La Hougue were defended by many batteries and forts, but the lack of regular maintenance ensured that these quickly fell into disrepair. In 1720 Tatihou was used for quarantining plague victims from Marseilles.
Vauban Tower is part of the UNESCO World Heritage site of Vauban Fortifications around the France.
References:The Château de Foix dominates the town of Foix. An important tourist site, it is known as a centre of the Cathars. Built on an older 7th-century fortification, the castle is known from 987. In 1002, it was mentioned in the will of Roger I, Count of Carcassonne, who bequeathed the fortress to his youngest child, Bernard. In effect, the family ruling over the region were installed here which allowed them to control access to the upper Ariège valley and to keep surveillance from this strategic point over the lower land, protected behind impregnable walls.
In 1034, the castle became capital of the County of Foix and played a decisive role in medieval military history. During the two following centuries, the castle was home to Counts with shining personalities who became the soul of the Occitan resistance during the crusade against the Albigensians.
