Its story

The story of Château de Blain.

The first castle at Blain was constructed around 1108 on the orders of Alan IV, Duke of Brittany, and formed part of the frontier defences of Brittany alongside Vitré, Fougères, Châteaubriant, Ancenis and Clisson. The fortress passed by marriage to the Clisson family in 1225; razed in 1260 after Olivier I of Clisson's revolt against the Duke, it was rebuilt by his son Olivier II with ducal permission.

In 1407 the castle became the property of the House of Rohan, Louis, Duke of Rohan, is buried here. During the French Wars of Religion it was besieged and set on fire in 1591, in fighting between the Duke of Mercœur and Jean de Montauban, the knight De Goust.

When Henri II, Duke of Rohan, became leader of the Protestant princes, Cardinal Richelieu ordered the castle dismantled in 1628, ending its military role; it was pillaged and burnt along with the Rohan family archives. The château later passed through several hands, including Marie Bonaparte in 1918, and its surviving towers and fortifications are classified as a monument historique.
