Tour Saint Clair

The Saint Clair Tower

Only the remains of a 13th century castle, the Tour Saint-clair is the testimony that Derval was in its time one of the strongholds of the Marches of Brittany. In 1598, the Edict of Nantes condemned the castle, then fief of the leaguers, to the demolition. The almost complete destruction was not realized immediately, as the fortress had to serve as a prison for Protestants captured during the siege of Port Louis in Morbihan. This place will then serve as a stone quarry for the Dervalese population. Explanatory panels on site.
