Lübeck Cathedral (, or colloquially "Lübecker Dom") is a large brick-built Lutheran cathedral in Lübeck, Germany and part of the Lübeck World Heritage Site. It was started in 1173 by Henry the Lion as a cathedral for the Bishop of Lübeck. It was partly destroyed in a bombing raid in World War II (1942), when the Arp Schnitger organ was destroyed by fire, but was subsequently reconstructed.
