Fodor's Expert Review Københavns Bymuseum

For an evocative collection detailing Copenhagen's history, head to this 18th-century building in the heart of Vesterbro. A meticulously maintained model of 16th-century Copenhagen is in front of the building. Inside there's also a memorial room for philosopher Søren Kierkegaard, the father of existentialism. The museum is free on Fridays.
