The Collegiate Church of Notre-Dame de Poissy is a Roman Catholic parish church in Poissy, Yvelines, France. It was founded by King Robert the Pious around 1016, but of the eleventh-century church, only the western bell tower-porch remains. Indeed, the collegiate church was rebuilt from the beginning of the twelfth century, and in particular between 1130 and 1160, in the late Romanesque style, then later in the early Gothic style, which manifests itself in the eastern parts. The future Louis IX was baptized there, a few days after his birth in Poissy, on April 25, 1214. This event made the church famous, and the baptismal font of this period is still preserved there. Throughout the Ancien Régime, a chapter of canons had its seat in the church, and for a long time ensured the parish service. It was dissolved during the Revolution, and the church was closed to worship, only to reopen again in 1802.

The Old Poissy Bridge, also known as the Old Poissy Bridge, is a masonry arched bridge that once crossed the main branch of the Seine over a length of four hundred meters and stretched for nearly a kilometer between Poissy and Carrières-sous-Poissy in the Yvelines department of France. This bridge, of which only six arches remain visible, is located 330 m downstream from the new Poissy bridge and 570 m upstream from the bridge on the island of Migneaux. It was an important commercial communication route in the region from the Middle Ages due to the passage of cattle from the Vexin and Normandy going to the livestock market in Poissy by the road to Rouen, the surrounding port activity, fishing and milling on its arches. It remained a strategic location during the wars until its destruction in 1944. It is the subject of a project to build a footbridge over its remains by 2024.
