Kwidzyn contains the partially ruined 14th century Brick Gothic Ordensburg castle of the Teutonic Order, namely the Bishops of Pomesania within the Order. Connected to the castle to the east is a large cathedral (built 1343-1384) containing the tombs of the bishops as well those of three Grand Masters of the Teutonic Knights.
The former Prussian fortress in Kwidzyn, which was occupied by the Teutonic Knights in 1233, received the city rights during the same year. In 1440 there was established the Prussian Union - today the Pomesanian"s cathedral chapter is the most precious historic and architectural treasures of Kwidzyn.
The wings of the castle with towers at the corners belonged to the defense system. Main tower today dominates the entire massif of the castle, which was also a bell tower lookout. The literally outstanding feature is a characteristic tower 'dansker' known as gdanisko of 1384. It was set by more than 50 meters from the west wing of the castle and the castle was combined with a long five spanning porches. Today the castle houses the Museum of the Castle. Kwidzyn history, its monuments and picturesque surroundings are enough attractions to visit for even the most demanding tourists.
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.
