Origin and history
The Musée Pillon originated from Raymond Pillon's legacy, which in 1977 offered its collections to the commune of Chaumont-en-Vexin. These objects, considered representative of the local heritage, were highlighted in 1993 and exhibited in the Heritage Hall of the Town Hall. The collections cover various fields: archaeology, paleontology, prehistory and natural sciences, illustrating the geological and human history of the region.
Paleontology occupies a central place with more than 1,000 fossils, witnesses of the warm seas that covered the Vexin between -80 and -35 million years. Shellfish, sea urchins, corals and shark teeth, often from sites that are now extinct, are presented. The prehistory, rich in hundreds of lithic tools (haches, scrapers, piercings), offers a dive into the daily life of the first inhabitants, supplemented by frescoes retracing human evolution.
The museum is also enriched by re-enactments of seals of the local nobility, models of monuments and old plans of the city. These additions, combined with Raymond Pillon's drawings, reinforce his pedagogical character. Located in a former 17th-century Recollet convent, the museum enjoys a historical setting, while highlighting local discoveries that are often unknown.
