Salt making on the Island
Salt making by evaporation of seawater was an important coastal industry from at least Saxon times until the late 18th century.
Sea water would be trapped in shallow pans and the water allowed to evaporate. Once just a salty brine remained, the final liquid would be boiled off over fires.
The decline during the 17/18th centuries resulted from a salt tax and also competition from cheaper mineral salt from inland mines in Cheshire.
Salt making on the Island was in two locations; Newtown estuary (from Norman times until about 1880) and Seaview (late 18th century until about 1820).
