The UNESCO World Heritage Site that includes the Iron Bridge is Ironbridge Gorge.
Ironbridge Gorge in Shropshire, England, is widely regarded as a birthplace of the Industrial Revolution. Its landscape preserves mines, furnaces, workshops, canals, and transport structures that illustrate the development of iron production and industrial technology in the 18th century.
The Iron Bridge opened in 1781 across the River Severn. Designed by architect Thomas Farnolls Pritchard and built with iron supplied by Abraham Darby III, it was the first major bridge made entirely of cast iron. The bridge helped demonstrate that iron could be used for ambitious structural engineering.
UNESCO inscribed Ironbridge Gorge in 1986. The designation covers a wider industrial landscape, not merely the bridge. A frequent confusion is with the Forth Bridge in Scotland, a later steel railway bridge opened in 1890 and separately inscribed as a World Heritage Site in 2015.
