Grand moulin de Ballan

Grand moulin de Ballan is a historic watermill in Ballan-Miré, a small town in the Indre-et-Loire department, a few kilometres southwest of Tours. Set on a bend of the Cher river, the building stands out for its striking "suspended" structure over the water, linked to the left bank by a metal footbridge.

Who built the mill, and when?

The mill was commissioned by Jacques de Beaune, superintendent of finances under King Louis XII, with construction completed in 1520. It was built from tuffeau, the pale limestone typical of Loire Valley architecture, on a channel bounded by two artificial dikes. The structure rests on two massive piers that support an arch, and it is beneath this arch that the large paddle wheel turns, driving the milling machinery.

What makes this mill unusual?

The Grand moulin de Ballan is best known for its "hanging mill" (moulin suspendu) system. The paddle wheel — now 6.30 metres in diameter and capable of up to 32 horsepower — is not fixed in place; it can slide vertically within a frame to adjust to changing water levels on the Cher. The current wheel dates from the late 19th century, replacing earlier machinery. This design was built for use on navigable rivers, and the Ballan-Miré mill is one of the last surviving examples of the type in France, and the only one left in the entire Centre-Val de Loire region.

How has the building changed over time?

Over the centuries the mill was altered and enlarged several times. An extension was added to the east facade, an overhanging corridor was built along the north side, and the piers dividing the current were repeatedly repaired due to the constant pressure of the river. After the French Revolution the property changed hands, and in 1831 it was bought by a miller, Jean Ribot, whose family ran it continuously until 1973. The mill itself stayed in operation until 1974, when a new, modernised milling facility opened on the left bank of the Cher.

Is the mill protected, and can visitors see it?

The Grand moulin de Ballan was partially listed as a historic monument (monument historique) by decree on 7 April 2005. Visitors can view it from the riverbank or by crossing the footbridge leading to it — it is one of the most photographed sights in Ballan-Miré, popular with anyone interested in industrial heritage or the history of the Loire Valley. Its picturesque setting on a curve of the Cher makes it a natural stop on riverside walks, close to other attractions in the countryside around Tours.
