Runcorn

Runcorn is an industrial town and cargo port within the Borough of Halton in Cheshire, England. It lies on the south bank of the River Mersey, where the estuary narrows to form the Runcorn Gap, and is located approximately southeast of Liverpool and southwest of Manchester. The Runcorn built-up area had a population of 61,145 at the 2021 census.

Runcorn was founded by Æthelflæd of Mercia in 915 AD as a fortification against the Viking invasion at a narrowing of the River Mersey. Under Norman rule, Runcorn fell under the Barony of Halton and an Augustinian abbey was established there in 1115. It remained a small and isolated settlement until the Industrial Revolution, when the 1776 extension of the Bridgewater Canal to Runcorn established it as a port linking coastal Liverpool with inland Manchester and Staffordshire. The docks enabled the growth of industry, initially shipwrights and sandstone quarries; in the late 18th and early 19th centuries, it was a spa and health resort, but this ended with the growth of polluting industries, especially soap and chemical works. In 1964, Runcorn was designated a new town and expanded eastward, absorbing neighbouring settlements and more than doubling its population.
