Welsberg Castle (Castel Monguelfo in Italian) lies in a strategic position above Casies Valley. The castle was built in 1140 by the two brother Schwinkher and Otto von Welsberg. This latest wanted the overhanging upon his lands. For more than 800 years the castle had been property of the von Welsbergs, one of the mightiest families in Tyrol, who obtained the title of Prince of the Holy Roman Empire in 1693 by the emperor Leopold I.
The construction can be divided into two main periods: the first Romanesque one in the XII century, and the second one, in the gothic and Renaissance period in the XVI century. The oldest element of the castle is the tall defensive tower built between 1126 and 1140. Around it the old Romanesque chapel, the residential building, and the other buildings had been built.
In 1765 the castle was destroyed by a fire and the upper floor had to be broken up and the roof brought down to the present height. Since then the castle had been forgotten till recent times when the heir of the Welspergs entrusted it to the Kuratorium Committee which completely restored it and made visits available during summer season.
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.
