Roof tower
With a roof tower - unlike the usual towers of village churches - the four side walls do not go from the foundation to the eaves of the tower roof. Only the west wall has a stone foundation, with the roof tower sitting on the west gable wall . The other three sides are supported by the roof ridge of the nave and a reinforced roof structure.
Sometimes roof towers are additionally supported by installing a gallery in the west of the nave, the supporting pillars of which extend into the roof structure. For structural reasons, the roof towers are therefore built from wood or half-timbered .
To be distinguished from the roof tower is the roof turret , which is not supported by the western gable wall, but sits in the middle of the roof ridge and is supported by the roof structure .
