Stonehenge has been occupied since around 8000BC with early work at Stonehenge beginning in 3000BC when an outer ditch and embankment was constructed, and standing timbers erected. From about 2500BC, Neolithic and Bronze age man started to bring Bluestones and Sarsen stones from Wales and the Marlborough Downs, it was completed in 1600BC.
