Ironbridge is a location next to the Iron Bridge, the world's first iron bridge built in 1779 over the Severn, from which the town derives its name. To make the bridge known, the formerly called Severn Gorge river valley was renamed Ironbridge Gorge. The place belongs to the civil parish The Gorge in the borough Telford and Wrekin, a unitary authority in Shropshire, England. The town quickly became a commercial and administrative center for surrounding industrial towns such as Coalbrookdale and Madeley on one side and Broseley on the other side of the River Severn. The owners of the bridge also built a hotel to allow the visit of the bridge and the surrounding industrial attractions. The place had a railway connection until 1964, when the great era of the coal and steel industry was over. In 1967, the Ironbridge Gorge Museum Trust was founded, a foundation for the preservation of the 35 industrial monuments in the Ironbridge Gorge, which are managed by the Ironbridge Gorge Museum. The Ironbridge Gorge Museum is an anchor point of the European Route of Industrial Heritage. In 1986 Ironbridge and the Ironbridge Gorge with their industrial monuments was declared a UNESCO World Heritage Site.
