Ørsted was the driving force behind the founding of the Technical University of Denmark in 1829 and served as its first director. The present-day department of applied electronics is named Ørsted·DTU in his honor.
The Copenhagen Fire of 1728 was the largest fire in the history of Copenhagen, Denmark. It began on the evening of October 20, 1728, and continued to burn until the morning of October 23. It destroyed approximately 28% of the city (measured by counting the number of destroyed lots from the cadastre), left 20% of the population homeless, and the reconstruction lasted until 1737. No less than 47% of the section of the city, which dates back to the Middle Ages, was completely lost, and along with the Copenhagen Fire of 1795, it is the main reason that few traces of medieval Copenhagen can be found in the modern city.
While the human and property losses were staggering, the cultural loss is still felt today. The University of Copenhagen library was without a doubt the greatest and the most frequently mentioned of such. 35,000 texts and a large archive of historical documents disappeared in the flames. Original works from the historians Hans Svaning, Anders Sørensen Vedel, Niels Krag, and Arild Huitfeldt and the scientists Ole Worm, Ole Rømer, Tycho Brahe and the brothers Hans and Caspar Bartholin were lost. Atlas Danicus by Hansen Resens and the archive of Zealand Diocese went up in flames as well. The archive of the diocese had been moved to the university library the very same day the fire started.
Several other book collections were lost as well. Professor Mathias Anchersen made the mistake of bringing his possessions to safety in Trinitatis Church. Árni Magnússon lost all his books, notes and records, but did manage to rescue his valuable collection of handwritten Icelandic manuscripts. At Borchs Kollegium 3,150 volumes burned along with its Museum Rarirorum containing collections of zoological and botanical oddities. The burned out observatory in Rundetårn had contained instruments and records by Tycho Brahe and Ole Rømer. The professors Horrebow, Steenbuch and the two Bartholins lost practically everything. And on top of all that a large part of the city archive of records burnt along with city hall.
Freetown Christiania, is a self-proclaimed autonomous neighbourhood and Anarchist community of about 850 residents, covering 34 hectares (85 acres) in the borough of Christianshavn in the Danish capital Copenhagen. Civic authorities in Copenhagen regard Christiania as a large commune, but the area has a unique status in that it is regulated by a special law, the Christiania Law of 1989 which transfers parts of the supervision of the area from the municipality of Copenhagen to the state. The rules forbid stealing, violence, guns, knives, bulletproof vests, hard drugs and bikers' colors.
Famous for its main drag, known as Pusher Street, where hash and skunk weed were sold openly from permanent stands until 2004, it nevertheless does have rules forbidding 'hard drugs', such as cocaine, amphetamine, ecstasy and heroin. The region negotiated an arrangement with the Danish defence ministry (which still owns the land) in 1995. Since 1994, residents have paid taxes and fees for water, electricity, trash disposal, etc. The future of the area remains in doubt, though, as Danish authorities push for its removal.
