Two adult skulls lie next to each other on the archeological excavation site at the 16th and 17th century Bedlam burial ground, uncovered by work on the new Crossrail train line next to Liverpool Street station in London, Friday, March 6, 2015. The excavation team estimate there to be 3,000 human skeletons at the site, which was a burial ground to the then adjacent Bedlam Hospital, the world’s first psychiatric asylum. The 118-kilometer (73-mile) Crossrail project to put a new rail line from west to east London is Britain’s biggest construction project and the largest archeological dig in London for decades.
