Initially built in the 11th century, the Saint-Aubin church underwent numerous restorations, notably from the 16th to the 19th century. This is what gave rise to the current building, mostly Gothic. The Vernon stone used to erect it is characteristic of other religious monuments in the region, such as the cathedrals of Chartres and Rouen and the collegiate churches of Vernon and Mantes-la-Jolie.
