The Burgtheater (Imperial Court Theatre) opened on 14 March 1741, the creation of the Habsburg Empress Maria Theresa of Austria who wanted a theatre next to her palace. Three Mozart operas premiered there. The theatre's first building adjoined the Hofburg at Michaelerplatz, opposite St. Michael's Church. The theatre was moved to a new building at the Ringstraße in 1888 designed by Gottfried Semper and Karl Freiherr von Hasenauer.
On March 12, 1945 the Burgtheater was largely destroyed in a bombing raid, and, one month later, on April 12, 1945, it was further damaged by a fire of unknown origin. After the war, the theatre was restored between 1953 and 1955. The classic Burgtheater style and the Burgtheater-German language were trend-setting for German language theatres.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.
