TK Elevator Test Tower

Germany's highest-above-the-ground observation deck (as of early 2025).
ThyssenKrupp Elevator built this tower for testing their elevators. The observation deck is open to the public (for a fee), and offers great views all around.

Up to date information for visitors are available on the tower's website:
