Bierzgłowski Castle was one of the oldest stuctures built by Teutonic Knights. The Gothic style castle was built between 1270-1305 to the site of previous castle (from the 1260s), which was destroyed by Lithuanians in 1263. Bierzgłowski castle has been rebuilt several times between 15th and 19th centuries. The castle has an unique ceramic relief in a one of portals. It depicts a horseman and two knights and is one of the oldest known Prussian ceramic artefacts.
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.
