St. Maria im Kapitol is an 11th-century Romanesque church located in the Kapitol-Viertel in the old town of Cologne. It was dedicated to St. Mary and built between 1040 and 1065. It is one of twelve Romanesque churches built in Cologne during this period.
Measuring 100 m x 40 m and encompassing 4,000 square metres of internal space, St. Maria is the largest of the Romanesque churches in Cologne. Like many of the latter, it has an east end which is trefoil in shape, with three apses. It has a nave and aisles and three towers to the west. It is considered the most important work of German church architecture of the Salian dynasty.
The first Maria im Kapitol church is said to have been built by Plectrudis, wife of Pippin in the 8th century. The foundations of a Roman temple from the late 1st century AD, dedicated to the Capitoline Triad, and those of a church from the year 690 AD, can be visited in the church's crypt.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.
