A mill for sale in Seine-Maritime (76) is typically tucked into one of the small valleys of the Pays de Caux or the Pays de Bray, where rivers such as the Béthune, the Austreberthe, the Varenne, the Yères and the Eaulne once powered watermills and flour mills for centuries. On this page, ma-propriete.fr brings together the mills for sale in Seine-Maritime: former watermills to renovate, flour mills converted into homes, and miller's houses with outbuildings. The department is among the richest in Normandy for small, still-recognisable valley mills.
You will also find price benchmarks based on actual sales, an overview of where these properties are concentrated, and the points to check before buying a mill, in particular how common flood zoning is along these narrow valleys and how variable the state of restoration can be from one property to the next. To prepare your project, read our white paper on creating a rural gîte, whose advice applies fully to a former Normandy mill, especially on surveying old stone and flint walls.
There are no official statistics dedicated to mills: sales are too rare and too varied (a ruin to restore, a habitable mill, a flour mill with a turbine). The most reliable market benchmark remains the price of country houses, which a habitable mill resembles, with a premium for the water, the character and the water rights, and a discount for the work required.

A departmental average hides large gaps. A smallholding to renovate, a restored longère with its outbuildings, a farmhouse on several hectares of land or a manor house with parkland do not sell at the same price, and the location matters as much as the building: coastline, tourist area, peri-urban countryside close to a job market or deep countryside. The table below shows the median price of country houses in Seine-Maritime (76) by type of municipality (cumulative sales from mid-2020 to 2025) and its change between 2021 and 2025.

| Residential coastline | €215,600 | €2,117/m² | +5.2% | 1,454 |
| Inland tourist areas (hinterland, mountains) | €183,300 | €1,970/m² | +17.9% | 155 |
| Peri-urban countryside (city catchment area) | €205,000 | €2,000/m² | +8.3% | 11,523 |

The Pays de Caux, a fairly dry farming plateau, is cut through by narrow valleys carrying the Béthune near Envermeu and Arques-la-Bataille, the Varenne near Bellencombre, the Saâne near Longueville-sur-Scie, and the Austreberthe near Barentin and Duclair. These rivers carried a very large number of watermills and flour mills, many of which survive as houses with a millrace and part of a water wheel, some still keeping a former millstone room intact.
The Pays de Bray, in the east of the department around Neufchâtel-en-Bray, adds its own bocage rivers, in a landscape of wet meadows and orchards. On the exposed Caux plateau itself, windmills once existed but are now very rare and sought after; the Seine estuary itself keeps almost no genuine tide mill in working condition.
The Béthune and Eaulne valleys, around Arques-la-Bataille, Envermeu and Neufchâtel-en-Bray, hold a large number of former mills accessible from Dieppe, in villages that have kept much of their flint building stock intact. Near Rouen, the Austreberthe valley and the Barentin and Duclair area benefit from good access via Rouen railway station and the A150 motorway. The coastal Pays de Caux, between Fécamp and Yvetot, adds mills on shorter valleys running down to the Channel, often near a small port.
Areas close to Rouen and the Seine axis are noticeably more expensive than the rural valleys around Envermeu or Neufchâtel-en-Bray, where a mill to renovate remains more affordable, particularly in the Pays de Bray, further from the main employment centres.
Always check the water rights attached to the mill (fondé en titre or holding an authorisation), the condition of the millrace, the weir and sluice gates, and the ecological-continuity obligations on classified rivers of the Pays de Caux and Pays de Bray, closely monitored by the water authorities. A small hydroelectric turbine project remains possible on some sites but needs a serious prior study, as these are low-flow watercourses.
On the building, in flint and brick or timber framing depending on the area, check for damp at the bottom of the valley and flood zoning, common along these Normandy rivers, along with the state of the roof structure, often in slate or thatch on the oldest examples. The outbuildings (barn, former flour mill, miller's house) suit a gîte project well, in a department popular with visitors to the Alabaster Coast and the meanders of the Seine.
