No Stone Unturned - Warburton, Greater Manchester

The team arrive at a field outside Cheshire where metal detectorists have made several valuable finds in the past, hinting the site was once a very active Roman settlement. However, the complete lack of finds causes serious concern amongst our intrepid explorers. They are joined by Mike Nevell from the University of Manchester, Roman historian David Shotter, and Robert Philpott from Liverpool Museum. Archeometallurgist Andrew Lacey fashions a simple Roman snake bracelet. Famously, this is the episode where Tony declares "We've done what we always threatened: after 160 programmes, we found - nothing."
