Celtic Gaul left to the northwest of Saint-Léger the largest known dolmen in the Paris region. Measuring approximately six cubic meters and between fifteen and twenty tonnes, it is known as the Ardoue stone or Ardroue and is located in the ancient carnute forest.

This dolmen is one of the few megaliths in the region and is indicative of human presence during the prehistoric era.
