The tower castle is located on an approximately rectangular mountain spur above the Emsbach. The spur drops steeply to the west, south and east. In the north there is a trench in front of the castle.
The core castle is 35 meters long and 18 meters wide. It has no keep. On the north side, the castle has a five-story shield wall, reinforced with tourelles, slightly bent, with a height of almost 20 meters. The entrance to the core castle was in the western shield wall. On the south side of the densely built-up core castle was the palas, whose outer walls have been preserved.
