Bockwindmühle, Post mill in Burgdorf, Germany.
The Bockwindmühle is a wooden post mill standing on a hill called Mühlenberg that rotates entirely around a central post to catch the wind. The whole structure turns to face the wind direction, rather than just the sails.
The post mill design emerged in 12th century Europe and spread across Central Europe over the following centuries. This example represents how grain processing technology developed in the region.
The mill shows how grain processing shaped daily life and community work in this region for centuries. You can see how important this trade was to local people.
The hilltop location provides good wind conditions for operation. You can see the internal mechanisms including the millstones and gears to understand how grain was ground.
The mill received special spring-mounted blades in 2005 that allow it to work more efficiently under different wind conditions. This modern upgrade shows how traditional structures are maintained today.
