As it stood in 1560
What Château de Blain looked like in its prime.
A compact mediaeval fortress of pale local stone sited beside the Nantes–Brest canal, formed of thick curtain walls and a ring of round towers topped with steep conical slate roofs and tall chimneys. A large drum tower with a corbelled, crenellated cornice stands by the main gate; the entrance is flanked by the South West and Drawbridge towers. A broad dry moat runs around the outer face and woodland rises behind the curtain walls.
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.
