Originally built by King Kazimierz to protect the money-making mining centre of nearby Olkusz, Rabsztyn actually consists of two separate castles – the original 14th century upper castle and the much-larger lower castle added at its foot in the 17th century in the Renaissance style. The Swedes saw to it that neither was inhabitable shortly thereafter during their 17th century invasion.
Today there is almost nothing to see of the upper castle, in fact most won’t even be able to discern the remnants of its walls from the rock surrounding it. The upper castle’s main feature was a cylindrical tower which irreverent fortuneseekers dynamited in the late 1800s. The walls of the lower castle still stand giving some indication of the size of this former strong-(but not strong enough)-hold, and recently the castle gate, several bridges and one of the towers was restored. Today it houses a small historical museum. All told, Rabsztyn's ruined splendour is pretty as a picture so don’t forget your clicker.
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.
