The Kleinmachnow Lock is the name given to the lock group of the canal stage in Kleinmachnow. It is the most striking structure of the Teltow Canal in Brandenburg-Berlin. The double lock, built in 1906, is a listed monument. The foundation stone of the lock was laid in 1901, and the ceremonial opening by Kaiser Wilhelm II took place in 1906.
The double lock, together with the open channel in its central dam and the northern lock built in 1940, forms the Kleinmachnow canal stage. The southern chamber has been out of service since World War II. The Spree-Havel Waterways and Shipping Authority is responsible for its operation and maintenance.
The architectural design of the lock superstructure in the area of kilometer 8.34 of the Teltow Canal near Kleinmachnow blends into the hilly landscape of the Teltow region. The lock is located southeast of the Seeberg hill and, to the east, is almost within touching distance of Lake Machnow. To the south lies the Bäketal nature reserve, and to the west, the view opens up to the Teltow Canal, disappearing into the forest – these are the scenic "trademarks" of the lock area, located in the immediate vicinity of the southwestern Berlin and northeastern Potsdam city limits.
