The Johanna windmill is a listed Dutch windmill in the Wilhelmsburg district of Hamburg.
It was built in its current form in 1875, but a windmill on this site has been known since 1585.
Grain was still ground on "Johanna" until 1960.
Today it is preserved as a monument to rural Wilhelmsburg.
The windmill is elevated on a dike above a complex system of ditches and ponds that are part of the Wilhelmsburg Dove Elbe.
Together with the historic half-timbered miller's house, it forms a closed ensemble, which is supplemented by a traditional half-timbered bakery built in 2013 based on a historical model.
Between the mill and the bakery, a paved square planted with a few trees offers open space that is used for the summer garden of the mill café, but also as a space for stands at the mill festivals.
