Initially, the building was built on a square plan, defended by 8 towers and surrounded by a moat. Over the course of historical events, the castle was pillaged and partially destroyed, before being classified as a historic monument and taken care of by the association “Les Amis du Vieux Château de Brie-Comte-Robert”.
