Château de Beaurevoir, Medieval fortress ruins in Beaurevoir, France.

Château de Beaurevoir is a medieval fortress where a cylindrical tower still rises from a mound overlooking the surroundings. The remaining foundations and moat system reveal the scale of this medieval defensive structure.

The fortress dates from the medieval period and served as a stronghold during the Hundred Years War. In 1430, its lord Jean II of Luxembourg held a notable prisoner before handing her over to English forces.

The tower is known as the Tour Jeanne d'Arc, named for the prisoner held here in 1430 by Jean II of Luxembourg before she was sold to the English. The castle was built at the start of the 14th century and described by the traveller Dubuisson as a massive fortress with many turrets. Its watchtower was classified as a monument historique on 10 December 1920.

The ruins are exposed on site and viewable from the exterior, requiring sturdy footwear due to uneven ground. Check local conditions before visiting, as the surrounding area can be damp, especially after rain.

The tower is named after Joan of Arc, who was imprisoned at Beaurevoir by Jean II of Luxembourg after her capture in 1430, before he sold her to the English. The cylindrical keep stands on a motte, and the castle ditches measured 40 metres wide and 10 metres deep.
