Ruines du Château de Montbel
Located uphill above the gorges of frou at 948 meters high, the ruins of the castle are on a long and narrow headland. From it we have a large point of view over the Entremonts and the mountains.
Known as Château de Montbel, the second fief of the Lords of Entremont is also known as Château du Gouvernement.
It was built following the gradual abandonment of the Château d'Entremont-le-Vieux in the early 14th century.
It is a strategic location, with an unobstructed view.
Destroyed in 1633 on the orders of Richelieu, it was bought back in 1694 by the Carthusian monks, who rebuilt it. As a result of the French Revolution, it became government property. Slowly, the château fell into disrepair.
Discover this site on foot, as well as the Noirfont swift, the Buis quarry, the gorges, the Chartreuse habitat, the hamlet of Le Château with its old sawmill and watchwheel... From St Pierre d'Entremont, it's a 3-hour walk.
