The cathedral first had an organ in 1415. The one that was built in 1868 gave many problems and had to be rebuilt five years later, but it was kept until 1940 because it made a nice sound. The organ that we see in the cathedral today was built in 1976 by the organ builder Rieger. There are four angel figures in the corners of the organ case. The organ has four manuals and pedalboard. All the organs during the cathedral’s history were built against the north wall because the sound was best there.
