Ancient Roman skulls found in underground London construction site

People have lived in London for more than 2,000 years and every now and then there is a reminder of just how old the capital city is. For example, construction workers for Crossrail were building a utility tunnel at Liverpool Street station recently, when they came across something unexpected - 20 Roman skulls. Initially, it was thought the remains were the decapitated heads of Queen Boudicca's rebels, who fought against the Roman occupation 1,900 years ago.

However, later archaeology suggested that the River Walbrook possibly eroded a Roman cemetery under Eldon Street, and the skulls had been washed downstream. The skulls were located in clusters, indicating they were caught in a bend in the river. Their location also indicates they were washed out of the burial ground during Roman times.

The Museum of London Archaeology is now analysing the finds, hoping to find out more about the age, sex and diet of these people of the past. Since Crossrail construction began in 2009, more than 10,000 items, spanning more than 55 million years of London's history, have been discovered. Report by Mark Morris.
