The Bethnal Green gas holders, built in 1866 and 1889, were used to manufacture and store gas produced from coal. Following the discovery of North Sea gas, they remained in use for storage. Now they are under threat. There is an active campaign to retain and conserve world’s second oldest surviving gasholder and its partner on their original in-ground brick tanks. English Heritage has already listed 12 other gas holders and there is a petition to save these historic structures. While the gas holders are over our border, they contribute magnificently to the Hackney skyline and members may wish to add their names to that campaign.
