Abstract[Bearbeiten]
In the Crypt of St. Maria im Kapitol in Cologne damages of stones and wall paintings are caused by cyclic crystallization and dissolution of the salts halite [NaCl] and nitratine [NaNO3] due to climate changes. Based on a research project between 1992 and 1996, the LVR-State Service for Historical Monuments, architects, scientists and restorers implemented certain measures and started a new monitoring concept in 2000 aiming to diminish the damages and salt concentrations in the crypt. The monitoring concept included the periodical collection of weathered stone debris coming off the walls, in addition to regular climate measuremen ts and salt analyses. Monitoring in combination with climate measurements are executed overa period of 20 years. Combining intervention in the room climate on the one hand and salt extractions on the other hand, turned out to be effective measures. Prerequisites for reaching this result are detailed insights into the interaction between building materials, moisture, salts, and environmental conditions. The case study demonstrates the effectiveness of a constructive cooperation of departments, architects, scientists and restorers, resulting in a lasting conservation concept for an object highly contaminated by soluble salts.
