Kröpcke clock, Turret clock in Mitte, Germany

The Kröpcke clock is a turret clock positioned at the junction of Georgstrasse, Bahnhofstrasse, and Karmarschstrasse in central Hannover. It stands at a main intersection within the pedestrian shopping area and is surrounded by stores and restaurants.

The weather column inaugurated on 8 November 1885 was funded by 2,800 marks in citizen donations and built to a design by Conrad Oertel, with a clock, city plan, railway timetable and European time comparisons. It survived the air raids of 8–9 October 1943 and the fire of 25 March 1945. On 25 October 1954 it was dismantled during Rudolf Hillebrecht's modernisation; a new clock by Karl Cravatzo followed on 3 October 1955, donated by the Lister Möbellager.

The clock doubles as a display case for changing art exhibitions and presentations, so what hangs inside it changes over time. Its spot in front of Café Kröpcke, a meeting place since the 19th century, keeps it a fixed point where people arrange to meet in the pedestrian zone.

The clock sits in the pedestrian shopping zone and is easily accessible by wheelchair. It serves as a natural reference point for navigation and meeting in central Hannover.

The clock's glass-sided body doubles as a display case for changing art exhibitions and presentations, so the landmark functions as a small public gallery on the pedestrian square. The 1955 clock was donated by the Lister furniture store, as recorded on a brass ring inscription.
