The Ille-et-Rance Canal, which connects Rennes and Saint-Malo, is the oldest canal in Brittany. It is made up of three sections, including the one at this location. The canal is then made up of the bed of the Ille.

Nowadays, only very few mills are still in operation in their original function, but they appear to hikers and cyclists along the river or canal as technical and historical monuments of an ancient craft tradition: Only through human ingenuity and the power of flowing water as driving energy, the heavy millstones inside were moved and so, for example, grain could be ground into flour (so-called grain mills) or oil could be pressed from fruits (e.g. olives) (so-called oil mills).
