The oldest fortress on the Lower Rhine is located in the historic Krefeld suburb of Linn. The former country castle belonging to the Electorate of Cologne has its origins around 1200. It was badly damaged during the Spanish Civil War of 1704.
The beautiful water castle is well preserved and includes a bailey, hunting lodge and tithe barn. In the accompanying Landscape Museum it is possible to view excavation finds from the days of Roman rule in the 5th century and the time of the Frankish princes. The special items included in the exhibition are the gilded articles buried along with the princes in the largest continuous and well-preserved burial site in Gellep-Stratum.
A further attraction is the mediaeval barge from the time of Charles the Great. Concerts and readings are regularly held in the great hall of Linn Castle. The castle grounds, including the surrounding park, provide an impressive backdrop for events of all kinds.
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.
