Le Vieux-Moulin (Old Mill) was built in the 16th century. The mill was originally built on a bridge across the river Seine that dated back to the 12th century. Initially constructed for military purposes, the bridge was subsequently repurposed for commercial activity and a total of five flour mills eventually sat upon its span.

Lacking proper maintenance and upkeep, however, the bridge deteriorated over time and was ultimately abandoned in 1651 after a flood caused structural damage that rendered the bridge unfit for use.

By the end of World War II, the Old Mill had sustained considerable damage and was in danger of collapsing. The people of Vernon took it upon themselves to restore and maintain the iconic structure.
