the most surprising discoveries so far have been Roman. In a small pit containing a small bluestone in the corner of the trench, itself cut into the main socket of one of the uprights, they found a Roman coin. Even more alarming, was the excavation of the large pit in the centre of the excavation, where right near the bottom they found a very small piece of what was indubitably Roman pottery. Was there a major reordering of the site in the Roman period? As Geoffrey Wainwright said, their small trench looked like an urban excavation, there were so many intercutting pits.
