Château de Bellegarde, Medieval castle in Bellegarde, France.

Château de Bellegarde, also called château des l'Hospital, stands at the edge of a body of water in Bellegarde, Loiret. Its red brick walls with grey stone trim comprise a tall pavilion with a steep slate roof and spire, a lower central wing with five dormers and three brick chimneys, and a round brick tower with a conical roof. The central wing's wall is covered by climbing foliage.

The site began as a fortified dwelling in the 12th century and transformed into a Renaissance castle during the 16th century under the l'Hospital family. A major redesign came later when the duke of Antin, son of Madame de Montespan, added the wings visible today.

The château takes its alternative name, Château des l'Hospital, from the de l'Hospital family, who owned it in the 16th and 17th centuries after the fief passed through Jeanne Braque to her husband Jean de l'Hospital. The name Bellegarde comes from the marquisate and short-lived duchy of Bellegarde. Today the former pavillon de la salamandre houses the town hall and the château is used for exhibitions.

The town hall now occupies part of the château, and the building is used as an exhibition venue. The pavilion d'Antin houses the café du château and the Charles Desvergnes sculpture collection. The grounds sit at the water's edge, and the surviving central basin and canals of the old gardens can still be seen.

The castle holds a significant collection of around forty plaster models created by sculptor Charles Desvergnes, an artist who won the Grand Prix de Rome in 1889. This collection is a rare example of work by an internationally recognized artist who left an artistic legacy in this location.
