Consett is a town of 27,000 people in the northwest of County Durham, England.Consett sits high on the edge of the Pennines. In 1841, it was a village community of only 145, but it was about to become a boom town: below the ground was coking coal and blackband iron ore, and nearby was limestone. These were the three ingredients needed for blast furnaces to produce iron and steel.The town is perched on the steep eastern bank of the River Derwent and owes its origins to industrial development arising from lead mining in the area, together with the development of the steel industry in the Derwent Valley, which is said to have been initiated by immigrant German cutlers and sword-makers from Solingen, who settled in the village of Shotley Bridge during the seventeenth century.During the 17th and 18th centuries, the Derwent Valley was the cradle of the British steel industry, helped by the easy availability of coal from Tyneside and the import of high quality iron ore from Sweden via the port of Newcastle upon Tyne. However, following the invention of the Bessemer process in the 19th century, steel could be made from British iron ore (which was otherwise too heavily contaminated by phosphorus) and the Derwent Valley's geographical advantage was lost, allowing Sheffield to become the leading centre of the British steel industry.
