EARTH burrowing moles are responsible for digging up some of Roman Britain's deepest secrets in a remote corner of West Northumberland.
They may be the bane of farmers across the land, but some moles are doing the human race a huge historical favour.
Epiacum, an isolated Roman fort close to the Cumbrian border 12 miles south of Hadrian's Wall, is a scheduled ancient monument and as such, any excavation is banned on site.
But humans has never yet introduced any law understood by Mr Mole – and scores of them are churning up Roman artefacts at Epiacum – or Whitley Castle – as they push out their molehills.
Whitley Castle stands on 1,000-acre Castle Nook Farm, and yesterday a team of 37 volunteers, under the watchful eye of English Heritage, sieved through those molehills to see what our subterranean allies had brought up.
