Zum Umgang mit mittelalterlicher Bauplastik
Although air pollution has been reversed, the most obvious problem is the black gypsum crusts. The prompt cleaning of the statues reduces further damage. The most effective protection of sculptures involves structural measures. Historical examples include the porch of the Singer’s Gate (around 1440), and current examples comprise the protection of cornices, gargoyles, and other exhibited building components from moisture penetration, mostly with lead sheet metal, and improving water flow to the building in general. During and after World War II, outdoor statues were brought inside to fill empty spaces caused by the destruction. Today, 3D scans, photogrammetry, drone flights, cherry pickers, and climbers are used for the studies. Sculptures are cleaned by lasers and microsandblasting, and missing places are sculpturally filled in.
