The first Teutonic castle in Zamek Kiszewski was surrounded by the Wierzyca and marshy grasslands. In 1454 the castle was destroyed by the armies of Gdańsk, and again in 1655 when it was taken over by the Swedes. The surviving remnants of the 14th century castle complex are its defensive walls with Teutonic keeps and a gatehouse. At the foot of the castle there is also a Neoclassical manor house, which dates back to 1856. At present, it is in private hands but is open for visitors.
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.
