On the evening of 2 January 1941 during the Second World War, the cathedral was severely damaged when a parachute mine was dropped near it during the Cardiff Blitz, blowing the roof off the nave, south aisle and chapter house.
The top of the spire also had to be reconstructed  and there was also some damage to the organ.
The Sunday after the bombing, worship took place in the Deanery.
Work soon began to clear the Lady Chapel and the Sanctuary and to repair the roof in these areas.
This was not completed until April 1942.
Further work was not possible until the end of the war and the repaired areas served as a place of worship until 1957.
Of British cathedrals, only Coventry Cathedral was damaged more, during the infamous Coventry Blitz.
Due to its importance, it received Grade I building status on 12 February 1952.

Major restorations and reconfigurations were carried out under architect George Pace of York, and the building was back in use in June 1958.
The Queen attended a service celebrating the completion of the restoration on 6 August 1960.
The Welch Regiment memorial chapel was constructed, and Sir Jacob Epstein created the figure of Christ in Majesty which is raised above the nave on a concrete arch designed by George Pace.

Pace presented two options to replace the pulpitum which was not part of the cathedral restoration done earlier by Pritchard.
One was for a baldacchino having four columns with a suitable painting beneath it.
The other was for a double wishbone arch topped by a hollow drum to house the division of the organ.
The figure of "Christ in Glory" would be installed on the west face of the drum.
This proposal was accepted by the Dean and the cathedral chapter.
They approached the War Damage Commission about whether funds initially meant for replacement of stained glass damaged in the bombing could be used for art in other media.
This permission helped to finance the Majestas figure.

In February 2007 the cathedral suffered a severe lightning strike.
 Particular damage was caused to the electrics of the organ, which was already in poor condition.
The instrument was not able to be used after the lightning damage.
 This prompted the 2007 launch of an appeal to raise £1.5 million for the construction of an entirely new organ.
