The dome of the New Town Hall, with its observation platform, is  high. The dome's lift is unique in the world in that its arched course follows the parabolic shape of the dome. It is often incorrectly described as a sloping lift up the dome and compared with the lifts in the Eiffel Tower, which actually travel diagonally only, without changing their angle of inclination.
The lift climbs the  shaft at an angle of up to 17° to the gallery of the dome, where the Harz mountain range can be seen when visibility is good. In the process, the lift moves  horizontally. During the trip, the two weight-bearing cables wind up on three double rolls in the wall of the shaft.
