Ironbridge is a village on the River Severn, at the heart of the Ironbridge Gorge, in Shropshire, England. The area around Ironbridge is described by those promoting it as a tourist destination as the “Birthplace of the Industrial Revolution”. This description is based on the idea that Abraham Darby perfected the technique of smelting iron with coke, in Coalbrookdale, allowing much cheaper production of iron. The Iron Bridge that crosses the river opened in 1781, it was the first arch bridge in the world to be made of cast iron, and was greatly celebrated after construction owing to its use of the new material.
