At the turn of the 13th and 14th centuries Jasenov castle belonged to the noble man Peter from Bačkov. He was formerly an ally of the king, Charles Robert, during the period of struggle with the family of Omodejs (of the Abov county). Later, because Peter turned agains the king and tried to murder him, his property was thus entirely confiscated and in 1317 most of it given to the faithful Philip Drugeth. Since then it was owned continously by the Drugeths, still their’s even in the 17th century as a part of the the domain of castles Brekov and Jasenov.
The first written document mentions the castle in the 1320s. The geographical position of the castle, built in the mountains away from the main provincial road was suitable for the function of a noble lord‘s seat. The nearby Brekov served the more typical purpose of a guard castle in the service of defending the local land or accomodating the king on his travels. George I Rákoczi’s army conquered and destroyed the Jasenov castle in 1644, during the third great uprising against the Habsburg empire. After the initiative of Count Andrássy, the vanishing ruin of the castle was partly conserved, several objects were roofed and the entrance part was fixed during the beginning of the 20th century. Today, however, only ruins remain.
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.
