Magdeburg Cathedral is the oldest Gothic building on German soil and is also one of the great medieval cathedral buildings. It was built in 1207 and consecrated in 1363. However, it was not completed until 1520, when the cathedral was extended to a total interior length of 120m and a ceiling height of 32m. The sacred building was built of different sandstones, which come from various mining regions in Germany.

Short description
The towers are in motion, striving apart and back together again as the seasons change. The 800-year-old sandstone disappeared under crusts, and weathering and salts harmful to the building also played their part in destroying it.

The structure showed cracks in some places, for which there were different causes. Improved statics and higher load capacity were achieved by stiffening the structures, frictional connection of the disturbed foundation and decoupling the components gate, passage hall and gate houses components. Particularly on the western side, intense blackening of the rock surface had built up, which was strongly interlocked with the ground. The deposits were composed of a mixture of soot and plaster. The cleaning process carried out in 1990 with the help of water could only result in a superficial cleaning. In 2002, the newly developed method of particle beam cleaning and cleaning by laser made it possible to remove soot and plaster without destroying the original surface.

On the façade surfaces of Kaispeicher A, there was a lot of efflorescence and lime aging, both signs of penetrating moisture. The damage patterns indicated a lack of frost resistance as well as no protection against driving rain. The listed façade required extensive frost and moisture protection, but was not allowed to undergo any visual changes.
