Süßmühle, Historical watermill in Nordgoltern, Germany.

The Süßmühle is a two-story half-timbered structure built on a rubble stone base with sandstone facing, positioned beside the mill canal. The building retains the architectural features typical of mills from its era, with its framework and foundation designed to work with water flow.

The von Alten family received permission to build this mill in 1622 near the Mindische Heerstraße, which would eventually become Federal Highway 65. Modernization came in 1903 with turbine installation, followed by electrification during the 1950s.

The mill displays craft details like a millstone set into its base and mill motifs decorating the balcony railing, telling the story of its former purpose. These ornaments reflect how important mills were to the community.

The mill canal is filled in around the building, though parts of the water installations in the weir area can still be made out. The bridge of today's Bundesstraße 65 over the lower mill ditch, built in 1785, is a separate listed monument nearby. The mill building itself is protected under object ID 31117513.

The name Süßmühle derives neither from sweetness nor from the Südaue stream, but from Middle Low German 'sûsen', meaning to rush or roar. This suggests the name was carried over from a predecessor mill on the site before the 1622 building.
