The archaeological museum of the Val-d'Oise, labeled Museum of France, is a site of the General Council.
Opened to the public since 1983, this museum is installed in a modern building which is integrated perfectly into the rural landscape of Vexin. On nearly 1,000 m2 divided into a dozen rooms, the museum preserves nearly 35,000 parts resulting from the archaeological excavations carried out on the territory valdoisien.
A selection of 3,000 objects constitutes the permanent collection of the museum presented in a chronological course which invites the visitors to discover the history of the department since its oldest past, geology (when the Val-d'Oise was under water 45 million years ago) until the more recent history of the men and the women (Prehistory, Antiquity, Early middle ages).
