Schlosskopf Fortress was built betweeen 1733-1741 according to the latest military knowledge. The mighty fortress lasted only 41 years - it had never gained any importance. In 1782, like all the other buildings, it was abandoned and slowly decayed. The imposing remains still leave the visitor with the feeling that it was impregnable.
As part of the Burgenwelt Ehrenberg, the 'Schaufestung Schlosskopf' with its guard oriel, Baroque impeller crane and observation tower has been staged since 2008, and offers another attractive insight into the architecture and defensive engineering of the time.You can reach the castle via a comfortable hiking trail, which leads families with children on the hunt for the legendary Schlosskopf treasure.
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.
