Cathedral of St Peter (German: Wormser Dom) is the principal church and chief building of Worms, Germany. Along with Speyer and Mainz, it ranks among the finest Romanesque churches along the Rhine. This magnificent basilica, with four round towers, two large domes, and a choir at each end, has an imposing exterior, though the impression produced by the interior is also one of great dignity and simplicity, heightened by the natural color of the red sandstone of which it is built. The Catholic Prince-Bishopric of Worms ceased to exist in 1800.
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 new windows were made by Mainz artist Alois Plum.
The cathedral is 110 m long, and 27 m wide, or, including the transepts, which are near the west end, 36 m (inner measurements). The height in the nave is 26 m; under the domes it is 40 m.
