Professor Mike Parker Pearson (UCL Archaeology) re-evaluates the timeline of Stonehenge's construction and sheds light on how it was used. The first Stonehenge began life as a cemetery with the original stone circle built 500 years before the version that we know today.
Professor Parker Pearson and his team also discovered that the second stage of Stonehenge (the iconic sarsen stone circle) was built 200 years earlier than thought, about 2500 BCE. Published on 21 Mar 2013
