Crossrail workers building a utility tunnel atLondon’s Liverpool Street Station have uncovered about 20 Roman skulls and pottery, found in the sediment of the historic river channel of the River Walbrook. Archeologists think that the skulls are from a Roman cemetery about 50 meters up river that was eroded and washed the bones downstream. Roman skulls have been found in the River Walbrook before, and it was once suspected they were decapitated heads of rebels from the 1st Century AD. But archeologists now believe there was no foul play. They said the bodies were probably buried in an area where there wasn’t much land available allowing the skulls to wash away by natural processes and clump together in a river bend. The skulls are being analyzed by the Museum of London Archaeology where they say some of the skulls date back to the 3rd or 4th centuries AD--before Romans began cremating their citizens.
