The Toile de Jouy Museum traces the history of the Toile de Jouy factory, created in 1760 in Jouy-en-Josas by Christophe-Philippe Oberkampf (1738-1815).

The Maison Léon Blum is the last home of the illustrious statesman, man of letters and architect of many social advances. All the rooms can be visited, from the kitchen to the modest bedrooms and the vast office-library.

This church (13th century), rebuilt and enlarged at the beginning of the 16th century, has a high, pointed bell tower flanked by four pyramidions, an unusual shape for the region.
