A unique 17th-century tower built by King Christian IV between 1637 and 1642 as an astronomical observatory for Copenhagen University. Instead of steps, a 209-metre spiral equestrian ramp winds up seven and a half times around the hollow core, allowing carriages and horses to transport heavy books and instruments to the top. The open platform features Europe's oldest active observatory and 360-degree vistas over historic city spires.
Highlights
- 209-metre cobblestone spiral ramp winding without steps
- Europe's oldest functioning astronomical observatory
- 360-degree panoramic viewing platform 35 metres above the city
- Library Hall gallery hosting rotating contemporary art exhibits
