Likava Castle (Likavský hrad) was referred to for the first time in 1315. Its construction started with the intention to have a guarding point over the passage across the river Váh and the trade route from the Váh Basin to Orava and further to Poland.
The castle owners, the noble family of Hunyady, gradually reconstructed and widened the core of the Castle and built the part called the lower castle in the second half of the 15th century. In the second half of the 17th century, the Thökölys" eventually finished the entire fortification system though it was of no use as it did not prevent the disaster at the beginning of the 18th century when the retreating troops of František Rákoczi completely pulled down the castle in 1707.
Likava castle gradually decayed in ruins. After a thorough reconstruction in recent year the tower Hunyadyho veža was opened to public. It contains the exhibition of the Castle history.
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.
