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:
The Arch of Constantine is situated between the Colosseum and the Palatine Hill. It was erected by the Roman Senate to commemorate Constantine I's victory over Maxentius at the Battle of Milvian Bridge in 312. Dedicated in 315, it is the largest Roman triumphal arch. The arch spans the Via triumphalis, the way taken by the emperors when they entered the city in triumph.
Though dedicated to Constantine, much of the decorative material incorporated earlier work from the time of the emperors Trajan (98-117), Hadrian (117-138) and Marcus Aurelius (161-180), and is thus a collage. The last of the existing triumphal arches in Rome, it is also the only one to make extensive use of spolia, reusing several major reliefs from 2nd century imperial monuments, which give a striking and famous stylistic contrast to the sculpture newly created for the arch.
The arch is 21 m high, 25.9 m wide and 7.4 m deep. Above the archways is placed the attic, composed of brickwork reveted (faced) with marble. A staircase within the arch is entered from a door at some height from the ground, on the west side, facing the Palatine Hill. The general design with a main part structured by detached columns and an attic with the main inscription above is modelled after the example of the Arch of Septimius Severus on the Roman Forum.
