In Stara Kuźnica, on the Młynkowska River, there is the only one in Poland, preserved in its original form, historic forge with a water system from the 18th century
Inside there is a large striking hammer thrusting close to 60 times per minute in a giant anvil, wooden box bellows, shears for cutting sheet metal, a furnace and other blacksmith tools. Near the wooden building of the forge there is a damming device that starts the hammer and bellows. It consists of a gate with wooden trough supplying water to the water wheel. The forge is now a museum exhibit.
