Sudweyher Wassermühle, Watermill in Sudweyhe, Germany

Sudweyher Wassermühle is a two-story half-timbered building with a mansard roof situated along the Hache River near the Lower Saxony Mill Route. Inside are exhibition spaces, municipal archives, and a venue hall in the renovated barn section, complemented by open grounds outside.

A mill belonged to the fief of Count Heinrich IV of Oldenburg-Wildeshausen around 1260, but this was probably a predecessor building. A undershot watermill existed in the 1420s, and the estate and mill were managed together from 1513 under Johann Frese. The present half-timbered mill was built in 1819, with additions in 1853, 1870 and 1907; milling ceased in 1963 and the community acquired and restored it in 1981.

Since 1984 the mill has housed the Kulturzentrum Weyhe and the municipal archive. The 1807 half-timbered barn, long called the Backhaus because bread was baked there, now hosts small-stage performances and film screenings. The site lies on the Niedersächsische Mühlenstraße and beside the Sudweyhe estate.

The mill stands at Im Mühlengrunde 15 and 17 in Sudweyhe, next to the Gutshof Sudweyhe and on the Niedersächsische Mühlenstraße. The waterwheel is driven by the Hache stream. The site is a listed building and has been used as a cultural centre and municipal archive since 1984.

A 1653 Merian engraving shows the mill driven by three water wheels, and a 1733 estate plan depicts the mill, its pond and the manor together. Besides animal feed and baking meal, the mill also served at times as a fulling mill and an oil mill.
