Falkenstein Castle is located at 1,268 metres above sea level and it is Germany's highest located castle. The stone castle was built approximately 1270–1280 by Count Meinhard II von Tirol on the borders of his land (Tyrol). Because of the unusual situation of the castle it has been interpreted in historical context as a symbol of opposition to the Duchy of Bavaria. The name Castle Falkenstein only came into use in the 15th century. The castle was largely destroyed in the 17th century.
King Ludwig II of Bavaria purchased the ruin in 1883 and commissioned several architects, the first being Christian Jank (the designer of Neuschwanstein), to replace the existing structure with a romantic castle. Jank first created a restrained design, but later envisioned the castle in a dramatic, High Gothic style. Georg Dollmann was employed to produce plans and elevations in the same year based on Jank's design. However, his modest and economical designs displeased Ludwig.
Ludwig died in 1886 before work on the castle proper could begin, and the many plans for Falkenstein were permanently abandoned. The ruin of Castrum Pfronten on the building site was never demolished.
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.
