The park was opened in 1988 and is located on the edge of the Oppidum of La Chaussée-Tirancourt. The visitor walks through a period of 600,000 years, from the Neolithic to the Gallo-Roman period. Houses from the Neolithic, Bronze Age and Iron Age were reconstructed in a scientifically sound manner. One can see flint workers, weavers, basket weavers and potters at work.

A beautiful park to discover with the kids. However, the archaeological part only opens at 2 p.m. They are carrying out work in the area of the lake and it is therefore closed.
