Jasov has the biggest monastery complex in Slovakia and its main church, dedicated to St. John The Baptist, is considered one of the country's most important late-Baroque buildings. Though the present complex dates from the 18th century, there has been a monastery since 1170. The first, probably made of wood, was destroyed by the invading Tatars in 1242. A Romanesque stone monastery soon replaced it and was rebuilt in a fortified style in the 15th century. The site was then completely levelled again in 18th century to make way for the present Baroque structure.
The current monastery was designed by the architect Anton Pilgram in 1766. The lavishly ornamented interior of the monastic church in Baroque style, the library of monastery, and conserved French garden are especially valuable. The monastery has 365 windows, 12 chimneys and four gates (representing the days, months and seasons of the year).
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.
