Rottweil elevator test tower

The TK Elevator Test Tower (TK-Elevator-Testturm) is an elevator test tower in Rottweil, Germany. It is owned by TK Elevator, who have their elevator research campus nearby. It stands 246 m (807 ft) tall and was built to test the company's MULTI elevator system. At 232 m (761 ft), the tower contains Germany's tallest observation deck. Completed in 2017, it was then the tallest elevator test tower in the world, as well as the second-largest elevator test chamber (next to a former mine shaft used by Kone).
