Château de Nandy, Protected heritage castle in Nandy, France.

Château de Nandy stands at the end of a straight gravel drive in Nandy, Seine-et-Marne. Its pale three-storey central block has a dark hipped roof with three dormer windows and a triangular pediment, flanked by lower two-storey wings with rounded dormer roofs and chimneys. Low mansard-roofed buildings frame the entrance courtyard, and a 27-hectare park surrounds the house.

Built in the 17th century as a hunting lodge, the château follows a square plan attributed to Androuet du Cerceau and was erected in the Louis XIII style. Its façade dates from the early 17th century. Nicolas de L'Hospital died there in 1644. Robert Cousin funded a restoration and opened it to weddings and film shoots; it was classified a monument historique in 1968.

The château is a private property that its owner Robert Cousin opened to the public, hosting weddings and film shoots there. It has served as a film set for productions such as Le Gendarme en balade in 1970 and Arsène Lupin in 2004, and for a Pascal Obispo music video in 2016. Each week it also provides the setting for the final episode of the show 4 Mariages pour une Lune de Miel.

The château is a private property, so it cannot be visited freely; access is arranged in advance, and the grounds are used for weddings and film shoots. The estate covers 27 hectares, with a park and a straight gravel drive leading to the entrance courtyard.

The castle's 27-hectare park is part of the estate, and the building itself was used as a set for the final episode of the French show 4 Mariages pour une Lune de Miel, where the winning couple is revealed on the perron as a car drives up the east drive.
