Moulin de la Blies

Moulin de la Blies is a historic mill on the banks of the Blies river in Sarreguemines, now home to a museum dedicated to earthenware production techniques. Standing at the edge of the town's former faience-making district, just a short walk from the centre, it's one of the most recognisable pieces of industrial heritage in this corner of Lorraine, near the German border.

What was this building originally used for?

The mill was built in 1841 by Alexandre de Geiger, owner of the Sarreguemines earthenware factory, who harnessed the flow of the Blies to power grinding equipment. It wasn't a flour mill — its job was to grind and prepare the ceramic paste that local workshops shaped into tableware, tiles, and decorative pottery. From 1825 to 1969 the site operated as one of several production units belonging to the wider Sarreguemines factory, which at its peak ranked among the largest earthenware manufacturers in Europe.

How did a working mill become a museum?

Once production stopped, the building sat unused for years before being restored and reopened to the public in 1998 as the Museum of Earthenware Techniques. The exhibition walks visitors through every stage of making a piece of faience — preparing the paste, shaping it, firing it, and finally hand-painting and decorating the finished object. A separate section of the display looks at the daily working lives of the factory's employees, giving the museum a social dimension alongside the technical one.

What can visitors actually see inside and outside?

Inside, the mill still holds much of the original machinery and tools once used to grind pottery paste, several displayed in the settings where they originally operated — a detail that makes it easier to picture the rhythm of a 19th-century manufacturing floor. Outside, the Jardin des Faïenciers spreads across what used to be workshops and storage buildings. The garden mixes greenery with the remaining stone walls and mineral features, creating a quiet outdoor space that sits right alongside the mill's industrial architecture.

Is this a locally significant landmark?

It is. In 2015, Moulin de la Blies represented the Lorraine region in "Le Monument préféré des Français," a nationwide French television competition to find the country's favourite landmark, finishing 9th overall. That result says a lot about how deeply the mill is woven into local identity and how well it stands for the industrial heritage of this border region with Germany.

Who is this visit best suited for?

The museum tends to appeal most to visitors interested in industrial history, craftsmanship, and ceramics, as well as families looking for an unusual, educational stop while in Sarreguemines. Because the visit combines an indoor exhibition of machinery with an outdoor garden, it works well as a change of pace — you get both a focused look at how things were made and a relaxed walk outside, without needing to travel between separate sites.

Frequently asked questions

What exactly was Moulin de la Blies before it became a museum? It was a working industrial mill built in 1841 that ground raw materials into ceramic paste for the Sarreguemines earthenware factory until 1969 — not a grain mill, but a supplier of the material used by local pottery workshops.

When did the building open as a museum? The Museum of Earthenware Techniques opened on the site in 1998, following the restoration of the former mill.

Is there anything to see beyond the indoor exhibition? Yes — next to the mill is the Jardin des Faïenciers, a garden laid out over the ruins of the factory's old workshops and storage buildings, combining plants with the remaining stone walls.

Has Moulin de la Blies received any national recognition? Yes, in 2015 it represented the Lorraine region in a nationwide French competition for the country's favourite monument and placed 9th overall.
