Access to the long, three-story building is only possible via a steep, narrow path from the east, which was widened in the 1950s during a restoration and secured by railings. The project was initiated and financed by Paul Gabriel, a citizen of Waltensburg who had emigrated to Canada.
According to dendrochronological investigations, the complex dates from the beginning of the 14th century; a year of 1312 is mentioned. There is no evidence of a previous building.
The inner wall and parts of the roof are formed by the overhanging rock. The beam bearings of the earlier access are still recognizable today. The complex is entered through a low entrance gate. A square window and a shooting hatch are embedded in the wall above the gate. The eastern part of the complex is a narrow tube about 1.5 to 2 m wide and, due to the cramped conditions, probably only served as storage and for defense. The south wall has broken several times and has been adapted to the natural course of the rock face. There are several slit windows for exposure as well as square windows with openings of approx. 70 by 50 cm.
The living quarters were in the western part of the complex, six meters wide. Remains of transverse walls, beam holes, windows with seating niches, a cloakroom in the west wall and a heap on the second floor reveal the earlier division. A relief found in the ruin showing a man with a short coat is in the Rhaetian Museum; a copy is exhibited in the Waltensburg local museum. The interior of the building wing is divided by two transverse walls, the foundations of which are still preserved. Some of the wooden beams that were still there were sawn off, which suggests that the beams that can still be used are planned to be demolished and removed. The most suitable roof is probably a pent roof attached backwards to the rock.
