The Trois Pierres dolmen is an ancient megalithic monument dating from the late Neolithic period (3400-2000 BC). It served as a collective burial ground for the inhabitants of the Seine-Oise-Marne culture. It consists of a short vestibule and a narrow room, separated by a vertical slab pierced by a circular hole, called the "soul hole," through which the bodies passed. The dolmen is surrounded by a peaceful and bucolic landscape, where you can also admire the menhir of the Bois de la Garenne, another prehistoric stone, located about 200 meters away.

The Church of Saint-Jean-Baptiste is the Catholic parish church of the commune of Chaumont en Vexin. Standing on the eastern slope of the hill of the old castle, it is only accessible from the town center via an alleyway ending in stairs or from the road via a discreet sloping lane. One of the most imposing religious buildings in the French Vexin region, it dates entirely from the 16th century. Its great homogeneity of style is due to its rapid construction, as it was completed in a single phase from 1530 to 1554. The square is a peaceful spot for a break overlooking the town's rooftops.
