The windmill with the unique Halladay turbine at the edge of Ruprechtov near Brno is a technical cultural monument. The mill was built in 1873 as a standard Dutch-type mill, with a four-blade windmill and a rotating roof. After a windstorm, the owner installed the Halladay turbine instead of the standard windmill: it is unique not only in Czechia, but also in Europe. Today, the turbine turns at a height of 16 metres above the ground, it has a diameter of 10 metres and weighs about 2 tonnes.
