LINCOLN, ENGLAND—Road construction in England’s East Midlands uncovered part of a medieval wall. “You can see pieces of pottery and bone through the layers allowing us to date them. Although we have what looks like a medieval dwelling, we do not know at this stage its purpose—whether it was residential or if a trade was carried out here,” archaeologist Leigh Brocklehurst said in a press release from the Lincolnshire County Council. The wall is thought to date to the twelfth century, when it would have been set back, behind buildings that faced the High Street. Its rough construction could indicate that it had been a home for daily wage workers who had moved into the growing town, then known as Wigford.
