Dzierżno Lock is one of the most interesting hydrotechnical constructions of the Gliwice Canal, which in 1941 connected the Upper Silesian industrial centers to the Oder River. It replaced the long-serving Kłodnicki Canal. The lock was put in use in 1939 and even then it was one of the most modern in the European waterways. The original machines and devices, which are industrial monuments, are still working here.
