Inselmühle Norderney, Heritage-listed windmill in Norderney, Germany

Inselmühle Norderney is a windmill built from granite and brick that rises above Marienstraße with four sails, a thatched roof, and a fox sculpture on its brake beam. The building now operates as a restaurant while preserving the structure and features of a traditional mill.

The mill was built in 1862 by miller Ihbe Lammers Hellmers from Ostermarsch to supply the island's bakers with wheat and rye flour, serving about 2,000 residents and 2,815 spa guests in 1864. In 1895 it was bought by miller Eilert Ibben Fleetjer, whose family owned it until 1962. A storm broke a sail in March 1951, and a fire destroyed the mill that April; it was rebuilt and milling resumed within days. The town of Norderney purchased it in 2022.

The mill is the only building on Norderney with a traditional thatched roof, showing how craftspeople built on the island in earlier times. It represents the milling and craft traditions that mattered to everyday life for island residents.

The mill stands at the corner of Marienstraße and Mühlenstraße, east of Norderney's centre, opposite the Napoleonschanze by the Kurpark. Volunteers run it for demonstration at irregular intervals, and a photo exhibition on its history is in the Conversationshaus at the Kurplatz. The mill was bought by the town in 2022 and its future use was still undecided that August.

The mill could process up to five tons of wheat, rye, and barley daily when wind conditions were favorable. This output was remarkable for a facility of its time and showed how well it was designed.
