During World War II, the cathedral was saved from intentional destruction at the hands of retreating German forces when "Wehrmacht" Captain Gerhard Klinkicht disregarded orders from the city commandant, "Sepp" Dietrich, to "fire a hundred shells and reduce it to rubble". On 12 April 1945, civilian looters lit fires in nearby shops as Soviet Army troops entered the city. The winds carried the fire to the cathedral, where it severely damaged the roof, causing it to collapse. Fortunately, protective brick shells built around the pulpit, Frederick III's tomb, and other treasures, minimized damage to the most valuable artworks. However, the Rollinger choir stalls, carved in 1487, could not be saved. Reconstruction began immediately after the war, with a limited reopening 12 December 1948 and a full reopening 23 April 1952.
