The Semperoper is the opera house of the Saxon State Opera and the concert hall of the Saxon State Orchestra. It is also home to the Semperoper Ballett. The building is located near the Elbe River in the historic centre of Dresden.
The opera house was originally built by the architect Gottfried Semper in 1841. After a devastating fire in 1869, the opera house was rebuilt, partly again by Semper, and completed in 1878.
In 1945, during the last months of World War II, the building was largely destroyed again. Exactly 40 years later, on 13 February 1985, the opera's reconstruction was completed.
The opera house has a long history of premieres, including major works by Richard Wagner and Richard Strauss.
References:The Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
