An ancient feudal fortress, the castle of Derval was considered in its time as one of the strongholds of the Marches of Brittany with its 9 towers. After experiencing prestigious sieges, including that of Du Guesclin, in 1598, it would fall under the axe of the Edict of Nantes which condemned it to demolition. The only remnant, the old keep, renamed Tour Saint-Clair and giving its name to the castle, still resists and bears witness today to the history of the castle known since the 11th century.
