Fürstliches Residenzschloß, in the center of the Detmold town park, is a fine example of Weser Renaissance style. In 1263, Bernard III of Lippe fortified the settlement at the crossing of the trade route from Paderborn to Lemgo over the Werre River with stone walls and granted it a municipal charter. In 1550, Detmold became the permanent residence of Count Simon III of Lippe. The counts were elevated to princes in 1789, and Detmold remained the capital of the small Principality of Lippe until the end of the World War I in 1918, when all princely states in Germany were abolished. Detmold Castle is still in the hands of the Princes of Lippe.
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.
