Moulin du Saut

Moulin du Saut is a ruined watermill wedged into a rocky gorge on the Alzou river, a few kilometres from the centre of Gramat, in the Quercy region of France's Lot department. The name comes from the nearby waterfall — "saut" means "leap" in French — which drops around 10 metres right where the valley narrows to just 7 metres wide, the exact spot the mill was built to exploit.

A history rooted in the Middle Ages

The earliest traces of a building on this site go back to the 13th or 14th century, though the mill remembered in local records has a slightly later origin story. In 1442, Hugues d'Aigrefeuille, then lord of Gramat, leased out the plot known as "Le Saut" specifically to have a mill built there. Hugues Tarnier constructed it, and by 1473 ownership had passed to Pierre Paul, a merchant from Rocamadour. Fortune did not favour the building for long: by 1577 it was already recorded as being in ruins.

A major rebuild followed between 1736 and 1739, commissioned by Antoine Raymond de Fouilhac, baron of Gramat, at a cost of 40,000 livres — an enormous sum for the era. The rebuilt mill housed four pairs of millstones, driven by Alzou river water channelled through three separate conduits.

From working mill to power plant to fire

The mill kept operating right up to the First World War. In 1924, an industrialist from Périgueux bought the site and converted it into a small hydroelectric plant, though output was modest. The venture was short-lived: a fire in 1925 destroyed the buildings entirely, leaving behind the picturesque ruins visible today.

What you'll find on site

Moulin du Saut now belongs to the town of Gramat, which has handed its upkeep to the Association des Amis du Moulin du Saut et de la Vallée de l'Alzou under a long-term lease. The association maintains the ruins and keeps the site open to visitors. The area has protected status as an Espace Naturel Sensible under the Lot department and is also part of the Natura 2000 network, so it's worth sticking to the marked paths rather than wandering off-trail.

How to get there?

The easiest approach is to drive to Gramat and pick up the signposted walking trail that follows the Alzou valley, known locally as the "Circuit du moulin du Saut." The route combines views of the waterfall and mill ruins with the dramatic gorge scenery typical of the Quercy region.

When to visit?

Spring and early summer are the best times, when water levels in the Alzou are higher and the waterfall is at its most dramatic. Summer brings lusher vegetation that can block some viewpoints, while autumn and winter often see a thinner flow of water.

Frequently asked questions

Can you go inside the mill? No — Moulin du Saut is a permanent ruin, viewable only from the outside and from nearby vantage points along the trail.

How long does the walk to the mill take? Depending on the route chosen, a round trip along the Alzou valley trail typically takes one to two hours.

Is there anything else worth seeing nearby? Yes, the Alzou valley hides several other former mills, and the famous village of Rocamadour and the Padirac caves are both close by.

Is entry to the ruins free? Yes, the site is open to the public at no charge, maintained by a local association operating under a lease from the town.
