Neurathen Castle (Felsenburg Neurathen), which was first mentioned by this name in 1755, is located near the famous Bastei rocks near Rathen in Saxon Switzerland. This was once the largest rock castles in the region, but today only the rooms carved out of the rock, passages, the cistern and rebates for the timber of the former wooden superstructure have survived. In the years 1982–1984 parts of the extensive castle were used to build the open-air museum.
The beginnings of Neurathen date back to the first half of the 13th century, however the site may have been inhabitated already in the Bronze Ages. The castle was inherited and sold, repeatedly besieged, conquered and burned in the wars between Bohemian and Saxonian armies. In 1485 it fell to the Duke Albrecht, but he never restored it and the castle eventually collapsed. During the Thirty Years' War, his ruins served to shelter the inhabitants of Pirna before the Swedes.
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.
