Neugebäude Palace is a large Mannerist castle complex in the Simmering dictrict of Vienna, Austria. It was built from 1569 onwards at the behest of the Habsburg emperor Maximilian II on the alleged site of Sultan Suleiman's tent city during the 1529 Siege of Vienna and apparently modeled after it.
It fell into disuse already in the 17th century and today stands in ruins. Under monumental protection since the 1970s, there are various efforts to restore the site.
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.
