Sonnenburg castle hill has almost 4000 years history. It has been an early historical settlement, Roman camp, early medieval castle complex, 750 years as a convent, stone quarry, ruins and poorhouse. In 1022 Count Volkhold gave the castle to Benedictines and it was converted as an abbey. The ruins of the apses, which grow out of the rock, archaic and replete with strength, tell of power and wealth, faith and devotion, but likewise of deterioration and decline.
Today’s Sonnenburg is a hotel with a reservoir of historical detail. Wandering through the house we come across impressive relicts from bygone times: Gothic frescos in the former chancel, coffered ceiling in the Residenzstube (“Residence Parlour”), Stone age spearhead and the “in-house Saint Clement” who rests in the crypt.
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.
