The Wealden Iron Industry — First Century Exploration 43 to 100 AD

The wide dispersal of sites across the eastern Weald and coastal river valleys reflects prospecting and assessment as much as systematic production — the Classis Britannica surveying a resource base inherited largely from pre-Roman Celtic ironworking.

The iron sites shown on this map represent the earliest phase of Roman exploitation of the Wealden ore deposits, broadly 43 to 100 AD. Many of these bloomeries were not established from scratch by the Roman military — they were pre-existing Celtic ironworking sites taken over and adapted after the conquest. The Romans recognised what was already there and immediately brought it under imperial control.

The distribution in this period is notably wide and dispersed across the eastern Weald, the Brede valley, and the coastal river systems draining toward the Channel. This reflects prospecting and assessment as much as systematic production — the Classis Britannica was surveying the resource base as well as beginning to exploit it. Beauport Park near Battle appears in this period already, suggesting early identification of the most productive sites that would later become major industrial centres under direct fleet management.

The road network shown is Margary's reconstruction from his Roman Roads in Britain (1955) and Roman Ways in the Weald (1948). The purple lines indicate proposed trackways and potential road corridors suggested by landscape and place name evidence, including the likely main export route via the Limden and Eastern Rother valley system toward the coast, with a probable focus at or near modern Etchingham. The Andredsweald forest boundary is shown in green, the estimated high tide coastline in pale blue, and the 5 metre tidal reach on the river systems in dark blue — reflecting the significantly higher sea levels of the Roman period which made the river valleys navigable much further inland than they are today, and which shaped the entire logistics of iron and timber movement to the coast.

By the end of the first century the military boundary enclosing the Weald — the burh chain on the Greensand ridge, the road cordon from Lemanis to Chichester — was being established. The dispersed exploration pattern of this period would consolidate in the second century into the managed industrial system that the Classis Britannica stamps at Beauport Park and Bardown attest.
