Built in 1296, Ehrenberg Castle offers everything you would expect from a medieval castle, defensive walls, tall towers and a lot of history. The gothic castle complex was home to emperors and kings, princes and tzars.
Ehrenberg was in the center of wartime battles several times. In 1546, the Protestant Schmalkalden occupied the fortress. In 1552, it was taken by the Elector Moritz of Saxony. In 1632 the Swedes stopped in front of its walls. In 1703, Ehrenberg fell into the hands of the Bavarians during the War of the Spanish Succession. From 1716 to 1717, Ehrenberg became the exile of Russian Tsarevich Alexei, who fled from his father, Tsar Peter the Great. Even in the Napoleonic Wars, it played a role. Beginning in 1971, Fridolin Schennach from Reutte took over the condemned ruin and initiated a rescue operation with numerous other idealists.
In 2014, the world's longest pedestrian suspension bridge was completed between the Ehrenberg Castle ruins and Fort Claudia, spanning the strategically important pass that these two structures were in part meant to guard. The length of the bridge 403 meters, with a height of 110 meters.
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.
