Château de Bourgon, 15th-century castle in Montsûrs, France

Château de Bourgon is a 15th-century stone castle on the road to Belgeard in Montsûrs. Its main hall and staircase date from the 15th century, while later rooms hold 18th-century woodwork. The walls are light grey and beige, with dark slate roofs, a pointed turret and rectangular windows with pale stone surrounds. A chapel from 1528 and a bridge over the dried moats stand on the grounds.

Jean de Montecler acquired the land of Bourgon in 1406, and his descendants held it until 1577. The main hall and staircase date from the 15th century and are built of stone; other rooms were added later, with 18th-century woodwork. In the 17th century the estate belonged to the Montmorency family. The castle, its bridge and portal have been classified as monuments historiques since 9 August 1996.

The name Bourgon refers to the estate, held from 1406 to 1577 by Jean de Montecler and his descendants, not to a family of that name. Inside, the "cabinet bleu" is the room of the marquise de Sablé, daughter-in-law of Urbain de Montmorency-Laval, and the chapel dates from 1528.

The castle stands on the road from Montourtier to Belgeard, in the commune of Montsûrs. The old moats are now dry, and a bridge crosses them to reach the entrance; the chapel dates from 1528. Visits concern the castle, its bridge and its portal, which are classified as historical monuments.

The castle was sold only twice in six hundred years. Jean de Montecler acquired the land of Bourgon in 1406, and his descendants held it until 1577. In 2004 it was bought by Alain and Isabelle Ducatillon, a couple from northern France, and the French Heritage Society gave a donation in 2009 for its restoration.
