Gate-tower
A gate tower (German: Torturm) is a tower built over or next to a major gateway.
Usually it is part of a medieval fortification. This may be a town or city wall, a fortress or a castle. The gate tower may be built as a twin tower on either side of an entranceway. Even in the design of modern building complexes, gate towers may be built symbolically as a main entrance.
