Szombierki Power Station

Stonking great cathedral to 20th century industry, with its sturdy clocktower, hall and chimneys, this opened as a coal-fired power station in 1920. In the 1970s it was converted to a hybrid power and heat station, thus heat was no longer just a by-product but intentionally created for local industry and housing, conveyed by steam pipes. It was largely redundant by the 1990s but kept on as a reserve, then closed in 2011. There's talk of making it a museum, but no-one wants the huge burden of maintaining this derelict complex. Occasional guided tours visit, don't wander in by yourself as it could collapse any minute.
