St Petersberg Castle is located on a hill to the west of the village of Silz. There is a pond to the south of the castle and the towering, five-story square keep is crowned with battlements. Beyond the castle is the so-called 'Schnitzer Tower', also known as the 'Faul Tower', which was originally the seat of the burgraves.The castle was originally an estate or imperial fief owned by the House of Welf and was the centre of the earldom in the Oberinn Valley. St Petersberg was first mentioned in documents dating back to 1090/97 and was referred to as 'Neuhaus' (new house) in the 12th and 13th centuries. Today, the castle is home to an all-male monastery and a convent is located at the foot of the Petersberg. The castle is privately owned and can only be viewed from the outside.
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.
