Middlewich, a town in northwest England, lies on the confluence of three rivers – the Dane, the Croco and the Wheelock. Most importantly for the history of salt making, it also lies on the site of a prehistoric brine spring. Following the Roman invasion, Middlewich was named Salinae on account of the salt deposits around it, as it was one of their major sites of salt production. During this time the Romans built a fort at Harbutts Field (SJ70216696), to the north of the town. Recent excavations to the south of the fort have found evidence of further Roman activityincluding a well and part of a preserved Roman road. Salt manufacture has remained the principal industry for the past 2,000 years. Salt making is mentioned in the Domesday book, and by the 13th century there were approximately 100 "wich houses" packed around the town's two brine pits. By 1908 there were nine industrial scale salt manufacturers in the town, with a number of open pan salt works close to the canal, however salt manufacture in Middlewich is now concentrated in one manufacturer, British Salt. The salt is sold as the Saxa brand by RHM, and by others e.g. supermarket own brands. Salt produced by British Salt in Middlewich has 57% of the UK market for salt used in cooking. (en)
