It certainly was not built on an idle whim. It has been estimated that the mound, which is 130 feet high and 100 feet across at the top, took 18 million man-hours to construct. The first phase dates from 2500 bc when a 16-foot mound was built. It was soon enlarged; then the plan was changed and a much larger mound was constructed in steps. Finally the steps were filled in to give a smooth slope.
The first excavation in 1776 consisted of a shaft dug down from the summit. In 1849 a tunnel was dug into the centre from the base of the mound, but nothing was found. Professor Richard Atkinson redug this tunnel in his 1968-70 excavations, through which much was learnt about the construction of the mound. But no one found any trace of a burial. It may still await discovery, perhaps hidden off-centre. Or Silbury may have had
