Rottenbuch Abbey was founded as an Augustinian monastery in 1073 on land granted by Duke Welf I of Bavaria. The Abbey church was constructed between 1085 and 1125 in the Romanesque style. The design of a crossing transept and free-standing tower is unusual for a Bavarian church. Rottenbuch was a center of papal loyalty during the Investiture Controversy. Under the patronage of Emperor Louis the Bavarian in the 14th century, together with its location on the pilgrimage route to Italy, Rottenbuch became the most influential house of Canons Regular in Germany.
In the 18th century the medieval interior of the church was redecorated in the ornate High Baroque style by painter Matthäus Günther and stuccoist Josef Schmuzer. With the secularization of the Bavarian monasteries under Montgelas in 1803 the monastic buildings were pulled down and the noteworthy library sent to a paper mill; the Abbey church became a parish church, which it remains to this day.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.
