Château de Montagu, Medieval castle ruins in Marcoussis, France
The square fortress features round corner towers and deep moats, with the Henri IV tower rising 17 meters above the surrounding landscape.
Jean de Montagu, superintendent of finances for King Charles VI, built this defensive residence between 1400 and 1408 near Paris.
The castle site now houses the Saint-Antoine horticultural school, where students learn environmental management and building preservation techniques.
The Heritage Foundation invested 200,000 euros to stabilize the tower structure and prevent water infiltration damage to the remaining walls.
The hexagonal vaulted lower room within the Henri IV tower, known as the dungeon tower, remains intact despite centuries of abandonment.
