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:Saint-Georges de Boscherville Abbey is a former Benedictine abbey. It was founded in about 1113 by Guillaume de Tancarville on the site of an earlier establishment of secular canons and settled by monks from the Abbey of Saint-Evroul. The abbey church made of Caumont stone was erected from 1113 to 1140. The Norman builders aimed to have very well-lit naves and they did this by means of tall, large windows, initially made possible by a wooden ceiling, which prevented uplift, although this was replaced by a Gothic vault in the 13th century. The chapter room was built after the abbey church and dates from the last quarter of the 12th century.
The arrival of the Maurist monks in 1659, after the disasters of the Wars of Religion, helped to get the abbey back on a firmer spiritual, architectural and economic footing. They erected a large monastic building one wing of which fitted tightly around the chapter house (which was otherwise left as it was).
