The Château de Fougères is a castle in the commune of Fougères in the Ille-et-Vilaine département of France. The castle was built on a naturally protected site, a rock emerging from a swamp surrounded by a loop of the Nançon river acting as a natural moat. It had three different enclosures: the first for defensive purposes; the second for day to day usages in peacetime and for safety of the surrounding populations in times of siege; and the last for the protection of the keep. In all it has an impressive 13 towers.
