Tranekær Castle was originally erected as a defensive fortress in the 13th century. The oldest part is the north wing, which dates back to about 1200. The 3m thick walls were added in the 14th century. The castle has been remodelled many times and today has two wings and an octagonal stair tower with a tall spire. It has belonged to the Ahlefeldt-Laurvig family for about 350 years. There is no admittance to the castle itself, but the castle park is open to the public.
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.
