Abstract[Bearbeiten]
The former Franciscan monastery church was mentioned for the first time in 1266 and is located on the periphery of the old town of Zeitz, Saxony-Anhalt, Germany. After several decades of neglect, the building was in the acute danger of collapse. In the 1990s parts of the roof collapsed and the groin vaults of the church were exposed to bad weather conditions. Along with the structural problems, the structurally damaging salts, principally magnesium sulfate, were regarded as the main cause of damage to the historical substance of the building. In many areas, the painting on the ashlar blocks and mortar was already lost or in acute danger of loss due to salt degradation. After making a map of the damages and prior testing, the ribs and the vault stones were extensively desalinated by cyclical sprinkling in order to ensure a contact-free treatment. In this case, the sprinkling proved to be both an economical procedure for a sustained salt reduction.
