From UNESCO:

Located in Upper Silesia, in southern Poland, one of the main mining areas of central Europe, the site includes the entire underground mine with adits, shafts, galleries and water management system. Most of the site is situated underground while the surface mining topography features the remains of the 19^th century steam water pumping station, which testifies to continuous efforts over three centuries to drain the underground extraction zone. It has made it possible to use undesirable water from the mines to supply towns and industry. Tarnowskie Góry represents a significant contribution to the global production of lead and zinc.
