Heinfels castle stands in the Puster Valley, near the entrance to the Villgraten Valley. Although the town was first settled by Huns around 500 AD, a castle was not mentioned until 1243. It belonged to the County of Gorz, and was expanded on the west side in 1500. In 1526, it was besieged by Michael Gaismair and 2,000 soldiers seeking to overthrow Catholic rule in the area. Today it is privately owned.
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.
