The graveyard was built on FINDING THE PAST the vegetable patch at Bethlem Hospital Following on from the significant archaeological finds at Liverpool Street in the 1560s to take overflow from last year, Crossrail are planning a further archaeological investigation of London’s cemeteries the site starting in October. During work to relocate local utilities, archaeologists have had tantalising glimpses into the past. The site at Liverpool Street has uncovered a rich deposit of archaeology and provides an intriguing insight into London’s history over the last 2,000 years including the Bedlam burial ground where over 2,000 burials were found. As utility works come to an end, archaeologists will step back in. The first phase of their works will include removing 200 burials from the site by carefully excavating each intact skeleton so that they can be reburied with care and respect.
