The Iron Age earthwork at Borough Fen is one of several #prehistoric enclosures built near the borders of the fen wetlands to manage large #communal herds of cattle grazing on the damp #pastures in summer, were centres for autumn roundups & seasonal assemblies for managing both.

It lies in the same #common wetland grazed by the whole of the #medieval Soke of Peterborough; that was the early medieval common pasture of the 5th/6thC Gyrwe (‘fen people’); & which, @PryorFrancis’s work suggests, had been common through prehistory.

There’s another at Stonea Camp, and others at Tattershall Thorpe in Lincs. and Arbury Camp on the outskirts of Cambridge https://twitter.com/drsueoosthuizen/status/1197567706586894338?s=21 https://twitter.com/drsueoosthuizen/status/1197567706586894338

‘Its region’, autocorrect, darn you - if you’re going to correct me at least BE correct. #OneJob
