What's Really Buried Under Liverpool Street Station?

Beneath Liverpool Street station, one of London's busiest railway termini, lie two thousand years of buried city. Roman skulls in a lost river. The site of England's first psychiatric hospital. A plague burial ground holding an estimated twenty-five thousand bodies. And a modern railway that has been bombed twice. The Crossrail project finally dug it all open, and what archaeologists found rewrote the history of London's dead.
