Speyer Cathedral, also known as the Imperial Cathedral of Speyer, is a Romanesque-style church located in the city of Speyer in southwestern Germany. It is one of the largest and most significant Romanesque structures in Europe and was added to the UNESCO World Heritage list in 1981.

The cathedral was built between 1030 and 1061 by the Salian dynasty as a symbol of their power and as a burial place for the family. The construction was led by Bishop Gebhard and was completed under Bishop Rüdiger. The cathedral has survived many wars, including the Thirty Years War, the Nine Years War, and World War II, although it suffered some damage during those conflicts.

The cathedral's most notable feature is its crypt, which contains the tombs of eight German emperors and kings, including the founder of the Salian dynasty, Conrad II, and the Holy Roman Emperor, Rudolf I of Habsburg. The crypt is also home to the remains of four queens and other prominent individuals from the Middle Ages.

The cathedral's exterior is characterized by its red sandstone walls and its four imposing towers, two of which flank the west facade and two of which form the transept. The interior features a nave and two side aisles with a series of groin vaults supported by massive pillars. The cathedral also contains a large baroque high altar, a Romanesque pulpit, and several beautiful stained-glass windows.
