In 2013, during excavation work for the Crossrail project, a mass burial ground dating from the 17th century was uncovered a few feet beneath the surface at Liverpool Street, the so-called Bedlam burial ground or New Churchyard. It contained the remains of several hundred people and it is thought that the interments were of a wide variety of people, including plague victims, prisoners and unclaimed corpses. A 16th-century gold coin, thought to have been used as a sequin or pendant, was also found. In early 2015 full scale excavation of the burials began, then estimated at around 3,000 interments.
