Christian IV built this 1630s observatory tower as a successor to Tycho Brahe's demolished Stjerneborg. The climb is the whole experience: a continuous spiral corridor, wide enough for horses, winding to an open platform above the city rooftops. The tower anchors the Trinitatis Complex, which also holds the Trinitatis Church and the original Copenhagen University Library.
What to look for
- The equestrian staircase: 7.5 helical turns with no steps anywhere on the ascent
- The open-air platform at 34.8 metres and the roofline view it delivers
- The Trinitatis Church entrance integrated into the same complex at street level
The ramp has no steps, so the climb is gradual but long — flat shoes are enough, no special gear needed.
