The ruins of the medieval castle »Kyffhausen« is located on the peak of the Kyffhäuser Mountains. From 1890 to 1896 the Kaiser-Wilhelm-Monument was constructed in these ruins. The building material for the castle especially for the voluminous monument was quarried in a stone quarry at the foot of the castle mountain. In 1891, the »Denkmalwirtschaft«, which was widened in the following years through numerous additions to a Building complex in a total length of 120m, was opened at the slope foot of the stone quarry. After the building, now called »Burghof Kyffhäuser«, stayed from 1990 to 2004 empty, substantial renovation works are currently running to establish a modern hotel and restaurant at the Kyffhäuser. As the owner of the Kyffhäuser castle, the monument, and the quarry, the district Sondershausen is responsible for providing security in order to exclude any danger to the directly adjacent hotels and commissioned the planning office of Schachtbau Nordhausen LLC with the planning of the slope stabilization.

The section to be secured has a length of about 200m and a maximum slope height of 52m. The particular difficulty is that the castle and monument come up to the top edge while the hotel is partly located at the slope foot. Due to the tight house construction, the accessibility via heavy construction machines is very limited. In addition to that, the area is a protected landscape, and the securing actions cannot affect the nature or tourist value of Kyffhäuser.
