Former "Junker factory", Industrial heritage building in Moutier, Switzerland

The former Junker factory is a multi-story industrial building at Rue Industrielle 123 in Moutier, built around 1860 and powered by a water wheel fed by a diverted channel of the Birs. It is the town's oldest architectural testimony to industrialization and is listed as a cultural property of local significance. The building is no longer in production; the adjacent Villa Junker houses the Musée du tour automatique et d’histoire de Moutier.

The industrial building was erected around 1860, powered by a water wheel fed by a diverted channel of the Birs. In 1880 the manufacturer Nicolas Junker set up his production there; after 1905 it became the first factory of the Tornos company. The main building was entered as "worthy of protection" in the cantonal heritage inventory in 2000 and has been listed as a cultural property of local significance (category C) since 15 March 2017.

The building's name recalls Nicolas Junker, who set up production here in 1880; after 1905 it became the first factory of the Tornos company. Nearby, the Villa Junker now holds the Musée du tour automatique et d'histoire de Moutier, devoted to automatic lathes and the town's industrial past. Old fruit trees stand between the buildings.

The building stands at Rue Industrielle 123, southwest of the town centre and west of the Birs, next to the Tornos works to the north. The Musée du tour automatique et d'histoire de Moutier occupies the neighbouring Villa Junker, with old fruit trees between the two buildings. The main building is listed as a category C cultural property of local importance.

The factory grounds include the Villa Junker, the founder's elegant residence that was later converted into a museum displaying the technological evolution of automatic lathe manufacturing. This unusual combination of factory and living quarters reveals how closely the entrepreneur was tied to his production operations.
