The history of the medieval village of Rochefort-en-Yvelines dates back to prehistoric times. Gallic oppida and castles subsequently succeeded one another on its promontory.

Places to visit:
- The Church of Saint-Gilles and the Assumption: a former feudal chapel offering magnificent views. The richly decorated "Chapel of the Princes" of Rohan Rochefort served as the family's funeral chapel until 1793. The adjacent cemetery is also worth a visit.
- The Château de Guy le Rouge, built in the 11th century, is unfortunately now just a ruin that is difficult to access.
- Château Porgès, visible from afar, was built in the early 20th century by the architect Mewes for the diamond merchant Jules Porgès. The building was inspired by the Hôtel de Salm in Paris, now the Palais de la Légion d'Honneur. Today it houses a golf course and hosts corporate seminars.
- Beautiful double wash house (1825) and a drinking trough with paved access. After leaving the church, take Rue Guy Le Rouge to the junction with La Rabette on the right.
- The wash house on the Remarde south of Longvilliers.
- The Haras de la Cense stud farm, which develops the method of ethological horsemanship, is located on the site of a fortified seigneurial residence, remodelled over time, which notably housed Henri IV and Gabriel d'Estrées.
