The Stonehenge Cursus is a large Neolithic cursus monument on Salisbury plain, near to Stonehenge in Wiltshire, England. It is roughly 3km long and between 100m and 150m wide. Excavations in 2007 dated the construction of the earthwork to between 3630 and 3375 BCE, several hundred years before the earliest phase of Stonehenge in 3000 BC. The cursus, along with adjacent barrows and the nearby 'Lesser Cursus' are part of the National Trust's Stonehenge Landscape property, and is within the Stonehenge and Avebury World Heritage Site.
