Moulin de Nançay

The Moulin de Nançay is a historic water mill standing on the Loing river in the commune of Nargis, in the Loiret department of France. Also referred to in some records as the moulin de Toury, it sits along the Route de Château-Landon, close to the border with the neighbouring town of Château-Landon.

What exactly is this structure?

The heart of the site is its pertuis — a bridge-weir spanning the Loing. It consists of two basket-handle arches resting on a single pier with a cutwater that splits the current. A paved roadway runs across the top of the arches, allowing crossing to the opposite bank, while sluice gates set beneath the arches were used to control the flow of water. This combination of road bridge and water-control gate is typical of mills built on rivers with variable flow.

When was it built?

The structure is dated to the turn of the 18th and 19th centuries. This was a period when a number of similar hydraulic works appeared along the Loing and its tributaries, originally built to power grain mills and later, in many cases, adapted for other industrial uses.

Is the mill a protected monument?

Yes. The Moulin de Nançay was listed as a monument historique on 3 May 1999, under reference number PA45000013. The listing covers mainly the pertuis itself — the arched bridge-weir with its sluice gates — recognised for its technical and historical value.

Can visitors go inside?

The property is privately owned. Its protected status does not grant public access to the interior, so the best way to see the bridge-weir is from the public road or the riverbank, without entering private grounds.

Where exactly is the Moulin de Nançay?

The mill stands at 1989 Route de Château-Landon, 45210 Nargis. Nargis is a small commune in the Loiret department, situated on the Loing river close to Château-Landon, a town known for its historic old town and medieval walls. It is worth noting that this is unrelated to the village of Nançay in the Cher department — a separate, distant location with no connection to this mill.

Why is it worth a stop?

The bridge-weir over the Loing is a tangible piece of pre-industrial water engineering that still shapes the river at this spot. For anyone travelling through the Loiret towards Château-Landon, it makes a short, natural stop — a chance to see how local water management was organised well before the industrial era.
