"This was a first for all of us on site," Morris said. "None of the team had ever excavated an intact stone coffin before, let alone a lead coffin as well."
They have now wrapped up their four weeks of digging at the site. The lead coffin has been taken away so that experts can carry out tests to figure out the best way of opening it without damaging its contents.
But, Morris said, other parts of the friary that the archaeologists tried to investigate this summer appear to have been completely destroyed -- meaning that some of the site's mysteries may never be solved.
