Nizhny Tagil iron and steel plant, Industrial heritage museum in Nizhny Tagil, Russia.

The Nizhny Tagil iron and steel plant is an open-air museum on the site of a works founded in 1725 by the Demidovs. Its buildings and equipment trace the full metallurgical cycle: blast furnace shop, rolling shop, open-hearth shop, power plant, machine shop and foundry. Preserved structures include an early 19th-century blast furnace building, an 1892 open-hearth furnace and bridge crane, and a water turbine.

The Nizhny Tagil ironworks was founded in 1725 by the Demidov dynasty and processed ore, charcoal, iron and copper on one site. After the Novotagilsky plant opened, the Kuybyshev works developed new blast-furnace methods for quality pig iron. In the Great Patriotic War it produced ferrochrome, ferromanganese and stainless strip for aviation. It closed in October 1987, and the museum opened in January 1989.

The plant's name lives on in the museum's full title, and its former workshops now host displays of factory equipment from the 1920s and 1930s. Among the exhibits are larch logs recovered during the 1992 dam reconstruction, preserved since the dam and plant were first built. The dam itself, begun in 1721 and rebuilt several times, still stands on the site.

The museum occupies a 30-hectare complex on the site of the former plant, with separate shops for the blast furnace, rolling mill and open-hearth furnace, plus outdoor displays of machinery and rolling stock. The grounds are large and partly unpaved, so allow several hours and wear sturdy shoes. The dam built in 1721 and rebuilt several times still stands at the edge of the site.

The dam on the site was built in 1721, before the plant itself, and has been rebuilt several times. Larch logs placed during its original construction were recovered during the 1992 reconstruction and are now shown in the factory equipment exhibition.
