Karneid Castle was probably constructed between the late 12th and early 13th centuries by vassals of the Prince-Bishopric of Brixen, an imperial estate of the Holy Roman Empire. The fortress stands perched dramatically on an inaccessible cliff face above the confluence of the Eggental and the Eisack rivers, on the historically resonant ancient border between the kingdoms of the Lombards and the Bavarii. The name 'Karneid' derives from the Latin 'cornus' meaning “horn”.
The courtyard with its fountain, the free-standing staircases and two-story loggia are especially worth noting for their picturesque quality.
Guided tours are available in the months of May, June, September and October.
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.
