Rundetaarn (The Round Tower), situated in the middle of Copenhagen, was built in the 17th-century by King Christian IV. Denmark was known in the world's astronomy thanks to astronomer Tycho Brahe at this time. When Brahe died in 1601, Christian IV wanted to continue with Brahe's research with a university observatory, resulting in the construction of the The Round Tower.
Around the observatory at the top is an outdoor platform where you will find the best view of Copenhagen's Latin Quarter. The 209 meter long sloping spiral path leading up to the observation platform on the roof is unique in European architecture.
Halfway up to the top you find the library hall, Denmark's first major university library, today used as an exhibition and concert hall.
