The coal mine Michal - National cultural monument, Důl Michal - Národní kulturní památka The oldest history of Michal mine is connected with an effort of the former Austrian state to support coal mining as an inevitable precondition for industry development. In 1842 a circular prospect pit in Michálkovice was founded with financing from the state mining fund and a year later it began to sink two pits there. The first of them, a Ferdinand pit, gave way in the 1880s. The other one was renamed as a Michal shaft after a deceased imperial adviser Michael Laier. In 1856 when the State Mine Enterprise performed considerable loses, the mine's ownership was passed to The Ferdinand Northern Railway Company, which had built and operated the railways network from Vienna through Ostrava and towards Polish salt mines, up to Czechoslovakian nationaisation in 1945, when it became a part of the Ostrava-Karvina Colliery syndikate, state enterprise. In 1946 the mine was renamed after a social-democratic deputy of The Austrian Reichstag Petr Cingr. The name has changed several times since then.
As a result of the heavy industry's transition in the Ostrava region, the Petr Cingr mine was closed down in June 30, 1993. The last elevator cage was hoisted on a spare winding machine in June 2, 1994. The coal pit was filled up in 1995. With the produktivity reduction in 1994, the whole area was overtaken by the Czech Republic's Ministry of Culture which established The Ostrava Museum of Industry there. It fused later with the Office For the Preservation of Monuments, Ostrava.
