Aerial photographs are rewriting the history of Hadrian's Wall. Images indicate there were hundreds - even thousands - of Iron Age settlements there long before the Romans. (photos, video)
"'What we thought we saw was a very militaristic landscape, very sparsely populated and all we saw was what survived at the surface,' said Dr David Woolliscroft from Liverpool University." When the aerial investigation started, the massive number of undefended, isolated farms gave rise to the idea that there had been working relationships with the area residents, rather than belligerant confrontation.
Among the discoveries is evidence of a fort built built near Vindolanda 50 years before the wall as well as an aqueduct built north of it and next to a native settlement.
