The church was struck by a fire bomb during an Allied air raid in 1943 and damaged repeatedly until 1945 when a high explosive bomb caused the collapse of parts of the vaults of the northern aisle. Due to that gap, it was feared that the building could collapse totally. However, all roofs and windows were closed quite soon, and by 1950 the vaults were reconstructed and the whole building stabilized. From 1972 to 1981 the church was restored once again. During those works, the chance was used for an intensive archaeological examination of the foundations and the graves under the floor. The only change of structures was the new rose window of the northern transept, but many of the Neo-Byzantine paintings disappeared. The design of the stained glass windows is totally new.
