City Hall Subway, New York
Built beneath New York’s City Hall, this subway station featured vaulted ceilings as well as chandeliers. It was designed by Rafael Guastavino in 1904 but was closed in 1940 due to lack of use once the Brooklyn Bridge station became more popular. Now it can be seen during a visit to the Transit Museum.
Power Plant IM, Charleroi, Belgium
Once known for being the biggest coal burning power plant in Belgium, the Power Plant IM was built in 1921. It was able to cool down 480,000 gallons of water, but at a great cost: it resulted in 10% of carbon dioxide emissions in the whole country. After many Greenpeace protests, it was finally shut down in 2007.
