Suffolk's Salt History
The unassuming Suffolk coastline was once a thriving hub for sea salt production, with a rich history stretching back 3,000 years.
Prehistoric beginnings
Long before the Romans, salt was a vital commodity for preserving food. Archaeological evidence on the Stour estuary at Stutton shows that Late Bronze Age communities (around 1000-800 BC) produced salt by heating brackish water over fires in ceramic basins and briquetage apparatus.
Roman industrialisation
During the Roman occupation, local production expanded to an industrial scale. The tidal marshes of East Anglia were ideal for salterns, leaving behind distinct archaeological markers known as 'red hills' – mounds of burnt, reddish clay waste. Sites have been identified near Hacheston, Snape and Iken.
Anglo-Saxon and medieval periods
Salt-making continued through the Anglo-Saxon era and into the medieval period, with the Domesday Survey of 1086 recording 20 'salinae' (salt pans) along the Suffolk coast. Salt marshes and production sites were closely tied to coastal ports like Dunwich and religious foundations such as the original site of Leiston Abbey.
Southwold’s post-medieval powerhouse
The final major chapter of Suffolk’s commercial salt industry took centre stage in Southwold. Following a devastating town fire, a commercial salt works was established in 1660.
The Southwold Salt Works
Seawater was flooded into a creek on high spring tides, left to naturally concentrate into a brine and then channelled via a wind pump (pictured) into a succession of coal-fired iron evaporating pans.
By 1750, the Free British Fishery created a soaring demand for salt to preserve the local herring catch. However, the business faced intense competition from Cheshire rock salt, heavy taxation introduced in 1702 and the eventual slump of the fishing trade.
Commercial salt production in Southwold officially ceased in 1893, surviving briefly as a provider of 'brine therapy' health baths before the final buildings were demolished in the 1930s.
A modern revival
For a century, Suffolk’s salt-making heritage remained confined to history books and archaeological sites. However, that ancient tradition is now being revived by Suffolk Sea Salt – returning traditional, sustainable salt-making to the Suffolk coast for the first time in over 130 years.
