Schattenburg castle was mentioned in the chronicle by the monks Ortlieb and Berthold in 1138. Muntifurt Castle, mentioned in the first half of the 12th century, may have housed vassals of the Earl of Bregenz, who ruled over the area at the time. At his coming to power (1182) the Earl Hugo I, the grandson of the last Earl of Bregenz Rudolf (1150), repositioned his residence to Feldkirch Castle, important for reasons of power politics and the control of traffic.
For 200 years, the Castle remained the property of the Earls of Montfort. Upon the death of the last of the Montforts, Rudolf IV (1390), the castle and the power that came with it passed to the Habsburgs. The Habsburgs ruled the estate through governors who lived in the Castle until 1773.
Only from 1416 until 1436 was their rule briefly interrupted, when it came into the hands of the Earls of Toggenburg. Duke Friedrich of Austria’s help in the flight of the antipope Johannes XIII turned out to be fatal for him. Not only was he outlawed in the name of the Emperor and excommunicated, he also lost all is possessions, among which Feldkirch. In 1825 the City bought the partially ruined Castle from the state for 833 Guilders. Today Schattenburg is a museum.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.
