Bois-Cornillé Castle, locally known as Château du Bois-Cornillé or Boiscornillé, lies north east of the village of Val-d'Izé in the Ille-et-Villaine department in the Brittany region in France.
Bois-Cornillé Castle dates back to the 13th century. By marriage it passed to Pierre Landais, Treasurer and Reciever General of the Duchy of Brittany and a financier of Duke Francis II, around 1482. Subsequently he rebuilt the castle. During the 16th, 17th and 18th century the castle passed through several families through inheritance and by sales. In 1854 it was finally bought by Paul le Cardinal de Kernier, Marquess of Kernier. His descendants still own the castle.
In the last half of the 18th century the old medieval castle was completely redesigned and enlarged into a neo-Gothic style mansion by the architects Jules and Henri Mellet for the Le Cardinal Kernier family. The octagonal entrance tower, known as the Gouyon Tower, is the only visible remnant of the medieval castle.
The castle is private property at present. I don't know its present use or if it can be visited. Its 19th century park can be visited during summer months. I like the Gothic style very much.
