[Preliminary entry.] The ironbridge at Ironbridge in Shropshire was the first major construction in cast iron in the world. The bridge was built over the river Severn in Shropshire by Abraham Darby III, grandson of the man who did so much to improve the production of cast iron and who founded the famous Coalbrookdale foundry. The bridge proved beyond doubt that large constructions could be made of iron and was thus the forerunner of such later works as the Eiffel Tower in Paris.
