To the east of the Weyer Tower there are still foundation walls of an approximately square building, which was once connected to the square tower by a wall. The tower (floor plan 14 by 10 meters) is only slightly raised from the slope by a shallow depression. To the south, the tower was secured by a steep slope, to the north there was a shallow ditch, which was adjoined by a pond (hence the name).
The outer walls of the tower are 16 m high. In the basement, the building is made of layered masonry with local stone ashlars. Inside, the beam holes for the wooden ceilings that used to exist can be seen. According to these, the building was seven storeys high. A protruding wooden battlement probably ran around the top floor, covered by a tent roof. The entrance was through a gate that was initially on the first floor, but this has now been bricked up and replaced by an entrance on the third floor. Small window openings can still be seen on the south side. On the west side, a round-arched door surrounded by four beam holes suggests the former bay window.
A Romanesque chapel extending over two floors can be seen on the east side of the tower; It still has a semicircular apse with an arched window facing the former courtyard. Remains of the old plaster with traces of simple painting are still preserved. Above the dilapidated chapel, two narrow flights of stairs from the fourth to the sixth floor have been preserved.
The tower ruins, on which trees were already growing, were secured and restored in 1992. The tower is freely accessible.
