The Sassenpoort is a gatehouse in the citywall of Zwolle, Netherlands. It was build in 1409 after Zwolle city became a member of the Hanseatic League in 1407. The city gates represent the wealth of this period. In the period between 1893 and 1898 restoration work took place. The dormers were made, and a neogothic spire clock tower was installed, replacing an earlier 18th century spire. In between the corner towers is a machicolation. From holes in the floor of this outer work, boiling oil could be thrown at enemies. The gatehouse is a rijksmonument since 1967 and is part of the Top 100 Dutch heritage sites. The gate now serves as a pedestrian road.
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.
