The oldest documentation known concerning La Rochette dates back to 1047.[citation needed]
Notable sites
The commune has many villas along the Seine as well as many estates and points of interest. In the centre of the village, the Maison Raulin (former estate of Gustave Raulin, architect for the City of Paris) stands out as a particularly tall structure. Nearby, the oldest building of the commune, l'Eglise Notre-Dame de la Visitation (dating back to the 13th century), can be found.[citation needed]
Across the church is the estate of Le Rocheton. Le Rocheton has had a number of different purposes. In the 19th century, the estate belonged to the Rochefoucauld family until being purchased in 1816 by Saint-Joseph de Lyon nuns. Their prime mission was to offer education and health care to children. In 1946, the estate was acquired by the YMCA. Because of its close proximity to Paris, the American army and the YMCA had used Le Rocheton as a halfway house during World War II. American soldiers who had been taken captive by the German army stayed at Le Rocheton before returning to America. In the 1950s, the centre began to accommodate asylum seekers from all over the world. It is still owned by the YMCA. Its primary purpose is a hotel for tourists, families and groups. Educational and professional training programmes are also offered.[citation needed]
Sports
The village has an equestrian centre as well as an indoor/outdoor tennis club. Le Rocheton YMCA also offers a number of activities such as mountain biking and basketball.[citation needed]
