Windmühle "Johanna"

Windmühle Johanna is a Dutch-style gallery mill with a square stone base and wooden gallery located in Wilhelmsburg, a district of Hamburg. It features four grinding mechanisms and multiple sack lifts that were used to process grain into flour.

This building was constructed in 1875 and was the fifth mill to occupy this location since 1585. The earlier structures were destroyed over time, leading to the construction of this more substantial stone version.

The mill carries the name of Johanna Sievers, the last miller who worked here, chosen as a tribute when restoration was completed. Today visitors can observe how grain was traditionally ground into flour and understand the practical knowledge that millers needed.

The ground floor contains a café where visitors can rest and attend regular events throughout the year. The mill itself operates on specific dates, particularly during Whit Monday, when you can watch the machinery in action.

Fresh bread is baked on the first Sunday of each month using flour ground by the mill's own mechanisms. This baking tradition demonstrates how grain becomes a finished food product through the mill's daily work.
