About
Quick facts: A gently sloping corkscrew ramp winds around the hollow tower for about 210 meters, letting visitors reach the summit without climbing a single stair. Visitors step onto a circular viewing platform with sweeping city panoramas and a small seventeenth-century observatory that still hosts occasional public stargazing nights.
Highlights: Built for King Christian IV in 1642, the tower's 36-meter height is reached by a 210-meter spiral ramp that winds 7.5 turns, wide enough that in the 17th century horses and carts were driven to the top to move telescopes and books. At the summit the old observatory's wooden floor creaks underfoot and brass instruments glint in thin winter light, leaving a faint metallic tang and the soft echo of centuries of footsteps.
Insider tips
- Wear comfortable shoes, the ramp is long but gradual.
- Head to the rooftop terrace for uninterrupted skyline photos at golden hour.
- Visit the historic library hall on the way up for ornate interiors and quieter space.
- Avoid weekend midday crowds by arriving right at opening or late afternoon.
