Château de la Grange, Historic castle in Yerres, France.

Château de la Grange is a castle featuring Louis XIII architectural style with symmetrical facades, mansard roofs, and traditional French construction materials. The structure displays the formal geometry and craftsmanship typical of residential chateaux in this region.

The estate of La Grange is first mentioned in 1389, when it was woodland cleared for a Parisian religious community; a fortified farm followed around 1581. Charles Duret, son of the physician Louis Duret, inherited it under Henri IV and had the present château built in 1617. Maurice de Saxe, marshal of France, bought it in 1748 and had the great gallery fitted out; the Gourgaud family held it until 1990.

The château's name comes from the wooded domaine de la Grange, first recorded in 1389 as land cleared for a Parisian religious community. Inside, the salon rose was decorated by the Swedish artist Gilles Marie Oppenord around 1740 for Pierre Nicolas Gaudion, and is credited with the birth of the rocaille or Louis XV style. Maurice de Saxe, maréchal de France, had the grande galerie fitted out after buying the estate in 1748.

The château stands on the Villecresnes plateau in the Bois de la Grange, along the avenue de la Grange (RD 94), north of the Yerres valley. The grounds are laid out with a dry moat around the cour d'honneur, an east forecourt with the main gate flanked by two square pavilions, and a west vista through the forest preceded by a water feature. Since 2000 the building has housed a hotel, so access to the interiors depends on the establishment.

In 1635 a grotto decorated with seashells was built into the southern dry moat, a detail most visitors walk past. During the Occupation the ground-floor grande galerie was turned into an aircraft-engine repair workshop while German officers lodged upstairs. In August 1944 General Patton's 2nd Armored Division passed through the grounds.
