Founded in 1127, the Saint-Séverin church in Oinville-sur-Montcient bears witness to the long history of this commune of Yvelines. However, the north wall of the nave is the only one to survive from this period. In a Gothic style, the church was then enlarged in the 16th century. Like many towns in Île-de-France, the church is part of the cultural heritage of Oinville-sur-Montcient and is classified as a historic monument.

These are two covered alleys, built between -2,400 and - 1,700 BC located in the city center. These are burial chambers which contained around sixty bodies. Seven covered aisles in total have been located within this perimeter.
