A mill for sale in Somme (80) is most often found along the Somme river itself, between the famous floating gardens of Amiens and the bay, or on tributaries such as the Avre, the Selle and the Noye, while the Santerre farming plateau was long a land of windmills. On this page, ma-propriete.fr brings together the mills for sale in Somme: former watermills in the wet valley, restored Santerre windmills, and converted flour mills. This dual tradition, river and wind, clearly sets the department apart from its Picardy neighbours.
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, particularly how extensive flood zoning is across the Somme valley and how different a watermill and a windmill are to restore. To prepare your project, read our white paper on creating a rural gîte, whose advice applies fully to a Picardy mill.
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.
How much does a country house cost in Somme (80)? According to DVF data (notarised sales) analysed by the ma-propriete.fr observatory, the median price of a country house in Somme (80) stood at €159,000 in 2025, with an average price of €166,279 and a median price of €1,565/m² of living space (2,315 house sales in rural municipalities over the year).

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 Somme (80) by type of municipality (cumulative sales from mid-2020 to 2025) and its change between 2021 and 2025.

|---|---|---|---|---|
| Tourist coastline | €200,150 | €2,275/m² | +11.3% | 676 |
| Residential coastline | €165,000 | €1,811/m² | +8.7% | 172 |
| Inland tourist areas (hinterland, mountains) | €150,000 | €1,667/m² | +5.3% | 144 |
| Peri-urban countryside (city catchment area) | €163,000 | €1,595/m² | +6.2% | 7,655 |

The Somme river, wide and marshy between Amiens and Abbeville, carried a very large number of watermills and flour mills, often set among peat-bog ponds or the river's multiple side channels, in a landscape close to that of the floating gardens. The Avre, the Selle and the Noye, quieter tributaries, also carried their share of small rural mills, many now converted into homes with the millrace preserved. On the farming plateau of the Santerre, around Péronne and Roye, with no notable watercourse, it was windmills that historically dominated instead, now very rare.
Towards the Bay of Somme, a few mills may have used the tide, but genuine working tide mills have largely disappeared from the Picardy coast, leaving partial remains or heritage reconstructions in their place.
The Somme valley, between Amiens and Abbeville, offers the largest number of habitable former mills, well served by Amiens railway station and the A16 motorway, making it the most active part of the departmental market. The Vimeu area, near Friville-Escarbotin, and the Ponthieu area around Abbeville add mills on secondary valleys, in a still strongly farmed setting. To the east, the Santerre, around Péronne and Roye, is the area to focus on for a windmill, when one comes onto the market.
Mills in the Somme valley, close to Amiens and the tourist sites of the floating gardens, sell well above the average for the Santerre and Vimeu areas, which are more affordable but more rural and less visited.
For a watermill in the Somme valley, check the water rights (fondé en titre or holding an authorisation), the condition of the millrace, the weir and sluice gates, and flood zoning, very extensive in this protected marshy valley of national wetland importance. Ecological-continuity obligations are strictly enforced there. A hydroelectric turbine project remains possible on some sites but needs a thorough prior study.
For a Santerre windmill, the condition of the timber frame and the rotating cap largely drives the restoration budget, often heavy for this rare type of building, and specialist craftsmen able to work on such structures are not always easy to find locally. In both cases, check the condition of the outbuildings; a gîte project makes most sense in the Somme valley, more popular with visitors to the bay and to the department's memorial trails.
