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 15 miles (24 km) southeast of Liverpool and 29 miles (47 km) 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.

The Silver Jubilee Bridge, Mersey Gateway, and Runcorn Railway Bridge span the River Mersey and the Manchester Ship Canal in Runcorn. Its location between Liverpool and Manchester and its links to the rail, motorway, and canal networks have made it a major centre for the manufacturing, logistics, and wholesale and retail industries.

The earliest written reference to the town is in the Anglo-Saxon Chronicle, where it is spelled "Rumcofan", literally meaning "a wide cove or bay". This word is derived from the Old English words "rúm" ("wide" or "broad") and "cofa" ("cave" or "cove"). Other historical spellings of Runcorn include "Rumcoven", "Ronchestorn", "Runckhorne", and "Runcorne".

Little is known about the early history of the settlement but isolated findings of objects from the Stone, Bronze, and Iron Ages have been made and there is evidence of a Roman presence in the area.

The first recorded event in its history is the building by Æthelflæd of a fortification at Runcorn to protect the northern frontier of her kingdom of Mercia against the Vikings in 915. The fort was built on Castle Rock overlooking the River Mersey at Runcorn Gap.

Following the Norman Conquest, Runcorn was not mentioned in the 1086 Domesday survey, although surrounding settlements were. William the Conqueror granted the earldom of Chester to Hugh d'Avranches, who granted the barony of Halton to Nigel of Cotentin. It is likely that Nigel erected a motte and bailey castle on Halton Hill in the 1070s.

In 1115, Nigel's son, William fitz Nigel, founded an Augustinian priory at Runcorn. In 1134, the priory was moved to Norton, about 3+1⁄2 miles (6 kilometres) away. In 1391, the priory was raised to the higher status of abbey. In 1536, the monastery was dissolved, and around nine years later, the buildings and some of the monastic lands were sold to Sir Richard Brooke who converted the habitable part of the abbey into a house.
