The Stonehenge Cursus (sometimes known as the Greater Cursus) is a large Neolithic cursus monument next to Stonehenge in Wiltshire, England.
It is roughly 3km long and between 100 and 150m wide. Excavations in 2007 dated the construction of the earthwork to between 3630 and 3375 BC. This makes the monument several hundred years older than the earliest phase of Stonehenge in 3000 BC. The cursus is part of the National Trust’s Stonehenge Landscape property.
