Borchs Kollegium was founded in 1690 by
Ole Borch who was a chemist at the University of Copenhagen. The original house, complete with Borchs library and chemical laboratories was destroyed, along with much of the city in the
Great Fire of Copenhagen in 1728. The house was rebuilt using remnants of the old walls, and stood ready three years and 5500
rigsdaler later, in 1731.
The second building 's, 1849 Because of Danish foreign policy in the beginning of the 19th century,
Copenhagen was the scene of some conflict with the British navy. In the
Battle of Copenhagen (1807) British forces decided to prevent Napoleon from getting hold of the Danish fleet. According to the history of Borchs Kollegium (see references) some of students of Borchs Kollegium participated in these skirmishes. Bombardments were especially heavy in the area around Vor Frue Plads and on the third day, September 4, fire broke out in the Kollegium and the building burned to the ground.
The third building The third building – the house that stands today – was built in 1824–25 under supervision of architect
Peder Malling. It was inaugurated on May 28, 1825. ==Residents==
