Blaker Fortress is one of the Norwegian fortresses which were constructed in the period of intense competition among the Baltic powers (Denmark-Norway, Sweden, Russia, Poland and the German states) for northern supremacy. In 1675 Gyldenløve indicated an intent to construct a fortress in the Glomma river where Blaker (a former township in Akershus) lies as part of his general program of Norwegian fortification upgrades. His objective was a stronghold available both to serve as a safe defensive position when necessary and a location to station troops who could take the offensive against invaders when the opportunity availed itself.
Blaker Fortress saw action in 1718, when it was surrounded by the invading Swedish army, but the siege collapsed upon the death of Charles XII of Sweden in front of Fredriksten Fortress. From 1917 to 2003 it was a place for education of craftsmen, art teachers and designers. Today, the old fortress is used for offices, cultural creativity, happenings, weddings, parties, exhibitions, meeting, courses and conferences.Historical walks on the fortress, ghost walks, theater, discourses, salute with canon and rental of costumes from the 1700s and 1800s.
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.
