The limestone Chatou building was first built on the foundations of a wooden church erected in the 11th century.
The bell tower, the oldest testimony, was built in the 12th century in a pure Romanesque style, a first choir having been built in the 13th century.
Around 1622, the nave was rebuilt with a nave vault and the main facade has a classical appearance.
During the Franco-Prussian War, the bombardments of the French army, stationed at Mont Valérien, damaged the church.
Paul Abadie (1812-1884), future architect of the Basilica of the Sacred Heart of Paris, was responsible for its restoration, which he carried out in 1871-1872. In particular, he added a spire to the bell tower and refurbished the interior while retaining the Romanesque facade of the building. Paul Abadie lived in Chatou where he was a municipal councilor from 1870 to 1875.
In 1880, the municipality of Monsieur Bousson decided on a new restoration campaign, this time planning to enlarge the church. The works were entrusted to the Catovian architect François Eugène Bardon (1843-1901). This one was inspired by Parisian Gothic models to rebuild the facade that we know today.
The stained glass windows date from the end of the 19th century with the exception of the stained glass windows on the south facade - demolished during the bombings of the Second World War - which were replaced by abstract stained glass windows commissioned from master glassmaker Emile Chauche.
In 1961, the central nave was lengthened thanks to a public subscription.
At the entrance to the bridge, the church is the sign of recognition of the history of Chatou
