English Heritage has been engaged in work at Silbury since May 2000 when a vertical shaft originally dug in 1776 re-opened up on the summit. After temporary stabilisation, a major investigative programme revealed further local problems associated with lateral tunnels dug at the base of the hill in 1849 and 1968. After much public debate and scrutiny, a scheme for permanent remedial works was agreed and work was duly carried out between 2007 and 2008.
The 2007/8 recording work identified numerous phases of the mound, suggesting that the archaeological stratigraphic sequence is considerably more complex than previously thought; the mound growing through many small events, rather than a few grand statements. The digital archive reflects the work that took place from the shaft opening on the summit of the hill in 2000 to the 2007/8 excavations and the assessment and analysis stages that followed.
