Château de Noirmoutier is very well preserved and a fine example of 12th century medieval architecture. The first traces of the castle appeared in 830 with the construction of a castrum by the abbot Hilbold, from the monastery of Saint-Philbert. It served to defend the monks and the island's population from the Vikings. The castle was rebuilt in stone in the 12th century by the feudal power who was trying to stabilise the region, notably by preventing Norman pillaging. The island at that time was under the control of the barons of La Garnache. The keep was built by Pierre IV of La Garnache, then an enclosure equipped with towers was built around the lower courtyard. In the 16th century, the castle was held by the La Trémoille family, then viscounts of Thouars.
The castle has resisted numerous attacks, like the English in 1342 and 1360, and again in 1386 under the command of the Earl of Arundelthe Spanish in 1524 and 1588. In 1674 it was taken by the Dutch troops of Admiral Tromp.
Château de Noirmoutier was sold in 1720 to Louis IV Henri de Bourbon-Condé who resold it in 1767 to Louis XV. During the French Revolution, the castle served as a military prison. During the 19th century, the castle was used as a barracks. In 1871, during the Paris Commune, insurgents were imprisoned there. In 1960, a house was built within the castle grounds by the governor of the island and the castle. Today, the keep houses the Noirmoutier Museum.
The keep at the centre of the castle is solid and rectangular. Built of rubble, it has three floors with the lords' residence at the top. The keep has numerous murder holes and defensive turrets at the corners. The rectangular fortification consists of two towers, a single gate and two watch turrets in the four corners. At the beginning of the 18th century, the towers were reconstructed and the keep adapted for artillery.References:
The Château Comtal (Count’s Castle) is a medieval castle within the Cité of Carcassonne, the largest city in Europe with its city walls still intact. The Château Comtal has a strong claim to be called a 'Cathar Castle'. When the Catholic Crusader army arrived in 1209 they first attacked Raymond-Roger Trencavel's castrum at Bèziers and then moved on to his main stronghold at Carcassonne.
The castle with rectangular shape is separated from the city by a deep ditch and defended by two barbicans. There are six towers curtain walls.
The castle was restored in 1853 by the architect Eugène Viollet-le-Duc. It was added to the UNESCO list of World Heritage Sites in 1997.
