Château de La Porte, Historical château in Sandillon and Saint-Cyr-en-Val, France

The Château de La Porte is an 18th-century château in Sandillon, Loiret, begun in 1776. Its light grey stone facade has reddish brick panels around the windows, a dark grey hipped roof with three dormer windows on each side of a central triangular pediment holding a round oculus, and a central entrance reached by a short flight of steps. Tall conical dark green hedges line the path to the building.

Claude de Loynes d'Autroche began building the château in 1776, and its chapel was finished in 1785. Count Bernard de Poncins owned the estate at the end of the 19th century. It was listed as a monument historique on 10 June 1992 and classified on 20 October 1995; in 2005 the businessman Claude Bébéar bought the domain.

The estate spans the communes of Sandillon and Saint-Cyr-en-Val, and its chapel was finished in 1785, nine years after building began. The painter Charles Pensée made watercolours of the domain in the 1850s and 1860s. Since 2005 the property has belonged to the businessman Claude Bébéar.

The property is situated southwest of Sandillon town center and can be accessed via departmental road D14. The location sits at approximately 100 meters in elevation, making the terrain relatively level and easy to walk.

French painter Charles Pensée documented the property in watercolor paintings during the 1850s and 1860s, capturing a visual record of the estate at that time. These artistic works offer a rare glimpse into how the château appeared through the eyes of a contemporary observer.
