Falkenberg Castle was founded probably between 895-898 AD, but not mentioned before 1154. In 1294 Aldsassen monastery bought it. In 1428 the monks successfully defend the castle against the Hussite invasion. During the Thirty Years' War in 1648 Hans Christoff von Königsmarck (Swedish-German soldier) conquered the castle and left it in ruins.
After been decayed for centuries, Friedrich-Werner Graf von der Schulenburg, a German diplomat and ambassador in Moscow, bought the castle as his retirement real estate. Following images from old paintings, he rebuilt the castle from 1936 – 1939. Schulenburg was part of the Operation Valkyrie, the failed assassination of Adolf Hitler. He was executed shortly after in 1944. The Gestapo confiscated the castle in World War II and arrested prisoners from the Flossenbuerg concentration camp. After the war, the Schulenburg family assumed ownership of the property.
Since its grand opening in 2015, visitors are invited to explore the castle’s museum and spend a night in the castle hotel. The castle also features a unique restaurant and a large knight’s hall for events.
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.
