Vaxholm Castle was originally constructed by Gustav Vasa in 1544 to defend Stockholm against shipborne attacks from the east, but most of the current structure dates from 1833-1863. The stretch of water below the building was formerly the main sea route to Stockholm. Thus, the fortress was strategically situated to defend the city from naval attacks. The castle was attacked by the Danes in 1612 and the Russian navy in 1719. Since the mid 19th century, its military importance has ceased. Today, it is home to the Swedish National Museum of Coastal Defence.
In 1970, it was used as a movie location for the pirate stronghold in Pippi Longstocking in Taka Tuka land. A scenic view of the castle may be seen from the car ferry which plies the short distance between Vaxholm and Rindö.
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.
