Between 1963 and 1982, the cathedral, which had been badly damaged, was rebuilt under the direction of Friedhelm Grundmann. Grundmann opted to use Obernkirchener Sandstein® for the solid stone altar and for the floor panels in the entire nave and adjoining rooms of the church.
The reconstruction of the cathedral took several decades to complete, as priority was given to the reconstruction of Luebeck’s Marienkirche. The towers and west side of the church were repaired first, followed by the eastern choir and, finally, the paradise porch on the north side of the cathedral. The reconstruction, headed by Friedhelm Grundmann and Horst Sandmann, was completed in 1982.
