Runcorn

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.
