Built under Christian IV, the tower winds its ramp up to a platform overlooking the rooftops of the old town. It is also one of the few attractions open late on certain winter evenings.
Our tipFrom October to March, the tower stays open until 21:00 on Mondays and Tuesdays, and the observatory opens from 18:00 to 21:00: a lovely way to end the day. Not included in the Copenhagen Card.
