Digging for Britain - Season 5 Episode 2 -

This episode is from the north of Britain, where finds include: evidence for the first Roman siege in Britain, including the biggest cache of Roman bullets discovered anywhere; Britain's most famous monastery - Lindisfarne - rediscovered for the first time since it was violently sacked by the Vikings 1,000 years ago; and the incredible discovery of the ancient Scottish man-made islands that entirely rewrite our understanding of Stone Age tech.
