The Stonehenge Cursus (sometimes known as the Greater Cursus) is a large Neolithic cursus monument on Salisbury plain, near to Stonehenge in Wiltshire, England. It is roughly 3 kilometres (1.9 mi) long and between 100 metres (330 ft) and 150 metres (490 ft) 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.
