Château de Grouchy

Château de Grouchy is a protected monument in Osny featuring classical French architecture with a symmetrical design, large windows, and a three-story central pavilion. The former noble residence sits within a 41-hectare park that includes wooded sections, a pond, and expansive lawns.

Construction of the present structure began in 1787 under Count Charles-Malo-François de Lameth, replacing an older 17th-century building. The redesign reflected the shift toward neoclassical style that marked the late 18th century.

The castle functions as a venue for art exhibitions where regional artists display their works in the historic rooms, bringing contemporary creativity into the classical setting. This blend of past and present makes the space feel alive with local artistic expression.

The grounds are accessible during daylight hours and the park can be visited free of charge, making it an open space for walking and exploration. The large outdoor area works well for leisurely activity and discovering different sections of the grounds.

The grounds contain a remarkable large-leaved linden tree that reaches about 30 meters (98 feet) in height and stands among the department's notable trees. This ancient specimen serves as a quiet witness to the site's long past and offers a striking sight during walks through the park.
