The origins of the settlement date to Roman times, when salt from Nantwich was used by the Roman garrisons at Chester (Deva Victrix) and Stoke-on-Trent as a preservative and a condiment. Salt has been used in the production of Cheshire cheese and in the tanning industry, both products of the dairy industry based in the Cheshire Plain around the town. "Nant" comes from the Welsh for brook or stream. "Wich" and "wych" are names used to denote brine springs or wells. In 1194 there is a reference to the town as being called "Nametwihc", which would indicate it was once the site of a pre-Roman Celtic nemeton or sacred grove.
