Built around 1150 by Guy III le Bouteiller de Senlis, Château de Montépilloy dominates the county of Senlis, thanks to its formidable keep, probably the highest of the royal domain at the time of its construction (around 1190-1200).
Testimony of a prestigious medieval past, the remains of the fortified castle include, in addition to the keep, an enclosure with a polygonal moat, an entrance gate through which one accesses the farmyard, a curtain wall with machicolation connecting the keep to the stately home and its semi-circular flanking tower.
The castle and its seigneury belonged to a succession of historical figures, each close to a king of France. The castle is open to the public
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.
