"An incredible structure with fascinating historical significance"
Exhibition about measuring the speed of light
Look down through the glass floor in the alcove

Climb a 17th-century spiral ramp all the way to the top of this bizarre tower for panoramic views across Copenhagen and beyond. Halfway up, peek into an exhibition about Ole Rømer, who first measured the speed of light using this very building.
