In Europe, post and tower mills are widespread.

The tower mill was built with a solid masonry roundhouse, where only the cap and the sails on the roof had to be turned in the wind direction, not the whole structure.

Based on their structural differences, two types are distinguished, the underdrift and the overdrift.

Underdrift windmills are smaller buildings. The stones are on the first floor, so the nuts or spindles drive the runner stone from below, which is why it is called underdrift.

Overdrift windmills are four-floor windmills; they could be made of adobe or bricks. This type works according to the principles above, but here the great spur wheel is located above the level of the stones – the stone floor – which drives the upper runner millstone from above, so it is the overdrift type.

In Hungary, in the Great Hungarian Plain, the former tower windmills were underdrift, clearly driven from beneath, later the ovedrift ones became widespread, in which sieves could be installed, so mill owners could compete with the steam mills.
