This 11th century tower was the bell tower of the Notre-Dame church.
In the 15th century a gallery was composed of four small bells and a spire taking the height of the building up to approximately 80 metres. This part was pulled down by French revolutionaries in 1794, destroying, at the same time, a part of the Notre-Dame church now separated from its bell tower by a road. The scar can still be seen on the side of the bell tower.
