The facility is located in a former production complex, including a puddling mill and a rolling mill, built in the first half of the 19th century and is a branch of the NOT Museum of Technology and Industry in Warsaw.
The plant in Sielpia was built in the years 1821-1841 on the initiative of Stanisław Staszic and Ksawery Drucki Lubecki in the Staropolski Okręg Przemysłowy (Old Polish Industrial Region). The construction of industrial facilities and a workers' housing estate was financed by the Bank of Poland. It produced about three thousand tons of steel products annually. The plant, which operated on charcoal, fell into decline at the end of the 19th century, but was closed only in 1921. Since 1934, it has served as a museum. During World War II, the museum was devastated and robbed by the Germans (72 wagons of iron, devices and equipment were taken away). In the years 1956–1959 the building was renovated, and in 1962 it was reactivated, this time as a branch of the Warsaw museum.
Currently, the exhibition includes a complex of former buildings, along with rolling and metallurgical equipment. The most valuable exhibits include: an 8-meter water wheel, designed by Filip de Girard, and about 30 machines from the turn of the 18th and 19th centuries, such as lathes, planers, presses, drills and machine tools. The outdoor exhibition includes a water wheel with a hammer from a 16th-century forge.
