Junkarsborg was a medieval castle in Raasepori. There are no documents left of castle, but archaeologists suppose that the castle was built in the early 14th century and was used until the beginning of the 15th century. Iron and bronze items, ceramics and silver coins have been found from the castle site. Remains refers to Rheinland in Germany and one theory believes that the castle was originally built by the Danish soldiers.
Nowadays there are only rectangular earth walls left. The ruins are on a forested island in the middle of the Svartå river and can only be reached on foot. Some reconstruction work has been done during 2005-2006 to improve the access to the island and its visual appearance.

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.
