Expression of the prosperity and pride of the city, the 57-meter bell tower is unique in the French landscape, despite invasions, wars but also lightning and fires; it eternally erects an impressive stone silhouette of rare lightness, which the light and the wind cross ight through. This bell tower is a real architectural feat!

This hybrid building brings together 4 centuries of architecture.
The early novel of the 10th and 11th centuries is expressed in the central portal as well as in the pillars on the north side of the nave.
The 12th century is found in the transept and the heart with superb capitals as well as in the beginning of the bell tower whose floors were not completed until the 13th and 14th centuries.
The enlargement of the church in the 14th century necessitated the resumption of the south arcades of the nave allowing the widening of the south side aisle.

In 1840, the Notre Dame church was listed as an historic monument.
