Wrangel Tower is named after Field Marshal F. E. H. von Wrangel. He arrived in Königsberg in 1809 as commander of the privileged Cuirassier Regiment. Wrangel Tower was built in 1843 as part of a defensive bastion of the ring of Königsberg. Water tower is surrounded by a moat, thick brick walls and ceiling to within three meters. Within 30 years, in connection with the development of long-range artillery, the construction of the tower was considered outdated, and in the early 20th century tower Wrangel was put out of the fortifications and to April 1945 in any military action did not participate.
During the assault of Königsberg during the World War II the tower was used as a base defense. April 9, 1945 the tower was blocked by Soviet troops, received minor damage and surrendered with the remnants of the Königsberg garrison. Now the tower hosts wholesale stores, warehouses and cafes.
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.
