Heemstede castle was first built in 1280 by Dirk van Hoylede from the region of Vlaardingen. Built, burned and rebuilt over the centuries, it was last torn down in 1810, after years of neglect. The monumental gatekeeper's house 'Nederhuys', built in 1630 remains intact as well as the foundations from the Middle Ages. The most famous owner of the castle was Adriaan Pauw, who bought it in 1620. He played a role in the Treaty of Munster, and built the bridge Pons Pacis to commemorate the peace treaty.
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.
