The Gasometer Oberhausen is a former gas holder in Oberhausen, Germany, which has been converted into an exhibition space. It has hosted several large scale exhibitions, including two by Christo and Jeanne-Claude. The Gasometer is an industrial landmark, and an anchor point of the European Route of Industrial Heritage and the Industrial Heritage Trail. It was built in the 1920s, and reconstructed after World War II.
In the 1920s the coal and steel industry in the Ruhrgebiet produced blast furnace gas and coal gas as a by-product of iron production and coking, while the steel industry as well as coking used large amounts these gasses or alternative fuels. As supply and demand of gas varied independently, sometimes excess gas had to be flared off, while at other times additional fuel had to be purchased. The Gasometer was built as a buffer: storing excess gas and releasing it again when demand exceeded production.
