Tower shaft
The tower shaft is the cylindrical or prismatic main component of a tower between the base and the tower spire or a cantilevered tower cage . In the case of very high towers, especially medieval church or other towers, the masonry is particularly thick in order to ensure the required stability.
Most of the towers consist of a tower shaft and a roof, although the ratio of their proportions can be very different.
A tower shaft is also found in other types of towers , such as lighthouses or modern radio towers . Here the tower shaft forms the slender, rising main part of the tower, without the superstructures and the tower cage.

In the case of flatter buildings, the storeys between the base and the roof are sometimes referred to in technical terms as the house or building structure. The facade is its coat.
