Werdumer Mühle, Ground-sailer windmill in Werdum, Germany

The Werdumer Mühle is a traditional Dutch-style grondzeiler windmill with white walls and large sails set in the North Sea coastal landscape. The structure shows the typical design of this mill type, with a heavy foundation anchored deep into the ground.

A mill existed on this site before the 16th century; a 1491 testament mentions a mill house, and a 1549 contract split the mill's income between two brothers. The present earth-hollander was built in 1748 by the lord of Edenserloog Castle, and it was completely rebuilt after severe storm damage in 1802. It remained in the castle lords' family until 1929, when the Post family acquired it.

The mill houses a heritage museum displaying household items and agricultural tools that show how rural people lived and worked. Visitors can see the everyday objects that were part of life in this farming region.

The windmill is accessible via Edenserlooger Street, which connects to County Road 14 and leads toward the town of Esens. The area is flat and best explored on foot or by bicycle, making movement around the site straightforward.

The structure preserves its original milling mechanisms that show how grain was processed in the 19th century. These intact functional parts allow visitors to understand the technical sophistication that supported regional grain production.
