The Cathedral of St. Peter (Wormser Dom, Worms Cathedral) is a basilica with four round towers, two large domes, and a choir at each end. The interior is built in red sandstone. Today, the Wormser Dom is a Catholic parish church, honoured with the title of 'Minor Basilica'.
Only the ground plan and the lower part of the western towers belong to the original building consecrated in 1110. The remainder was mostly finished by 1181, but the west choir and the vaulting were built in the 13th century, the elaborate south portal was added in the 14th century, and the central dome has been rebuilt.
The ornamentation of the older parts is simple; even the more elaborate later forms show no high development of workmanship. Unique sculptures depicting salvation stories appear above the Gothic-era south doorway. The baptismal font contains five remarkable stone reliefs from the late 15th century. The church's original windows were destroyed by bombing in 1943; between 1965 to 1995 Mainz artist Alois Plum crafted new windows.
The cathedral has three bells, all of which are housed in the southeast tower. They were cast in 1947 by Albert Junker to replace the old peal of four bells destroyed in World War II.
References:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
