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. 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.
Radiocarbon dating of a red deer antler pick discovered at the bottom of the western terminal ditch suggests that the Stonehenge Cursus was first constructed between 3630 and 3375 BCE. It is just under 3 km long, and is roughly 100m wide. Because of a slight difference in the alignment of its north and south ditches, it widens to a point nearly 150m near its western end. It is roughly aligned east-west and is oriented toward the sunrise on the spring and autumn equinoxes. There is a (later) Bronze Age round barrow inside the western end of the enclosure, and a large Neolithic long barrow was constructed at its east terminal. The Stonehenge Riverside Project excavated the remains of the long barrow in 2008 to determine if the barrow predated, or was contemporary with the cursus itself. The ditches of the cursus are not uniform and vary in width and depth. The eastern ditch is fairly shallow, as is the southern ditch – being only 0.75m deep and 1.8m wide at the top. At the western terminal, the ditch is 2m deep and 2.75m wide.
Like most cursus, its function is unclear, although it is believed to be ceremonial. The length of the cursus, running roughly east west, crosses a dry river valley known as Stonehenge Bottom. This may have been a winterbourne during the Neolithic era. If so, this would give it similar characteristics to other cursus, such as the Dorset Cursus, and it may be related to a ceremonial function. It has also been suggested that the Stonehenge Cursus acts as a boundary between areas of settlement and ceremonial activity. The cursus is also aligned on the equinox sunrise which rises over the eastern long barrow.
William Stukeley was the first antiquarian to identify and record the Stonehenge Cursus, although he incorrectly assumed it to be Roman in origin. In 1947 John FS Stone excavated a small area of the southern ditch toward the west end of the cursus. He discovered a small chipping of bluestone and an antler pick in a specially dug recess that dated from approximately 2500 BCE.
In 2007, the Stonehenge Riverside Project dug three trenches at the western end of the cursus, discovering the antler pick at the western terminus ditch. A trench in the northern ditch uncovered a sherd of pottery tentatively dated to the 4th millennium BCE. A trench at the southern ditch found evidence of recuts into the original ditch, c. 2500 BCE (when Stones antler was deposited), and again between 2000 and 1500 BCE.
Amesbury 42 Long Barrow
Just beyond the eastern terminal of the Cursus is a Neolithic long barrow, oriented north-south. It was noted by William Stukeley in 1723 and Richard Colt Hoare in 1810, and was excavated by John Thurnam in 1868, recovering an ox skull and some secondary inhumations. The barrow has since been levelled and is now underneath a bridleway running along King Barrow Ridge. The 2m deep eastern ditch of the barrow was excavated once in the 1980s by Julian Richards and his team for the Stonehenge Environs Project, although they failed to find any dateable material. The Stonehenge Riverside Project excavated the ditch once more in 2008.
As long ago as 1979, the Royal Commission on Historical Monuments recommended that the barrow should be better protected, by diverting the bridleway around it and clearing the woodland between it and the cursus. This is yet to happen however.
750m northwest of the western end of the Stonehenge Cursus lies the Lesser Cursus, a 400m long and 60m wide earthwork oriented west-southwest and east-northeast. Although its banks and ditches survived into the 20th century, ploughing since World War II has levelled it and it is only visible today as a cropmark. The Lesser Cursus was excavated in 1983 as part of the Stonehenge Environs Project. They discovered that the original earthworks was only half its current length, but was then extended. They also concluded, as had previously been thought, that it had no eastern terminal. The ditches and banks simply stop leaving the eastern end open. The project also discovered several red deer antler picks that have dated the monument to approximately 3000 BCE.
The Stonehenge Cursus is entirely located in the Stonehenge Landscape property's open access land and is therefore free to visit. It is located 700m north of Stonehenge and is easily reached via the bridleway heading north from Stonehenge car park. The Lesser Cursus is on arable land, although a permissive path goes near it. However, as it is only visible as a cropmark, there is nothing to see. Amesbury 42 long barrow is under a bridleway at the far eastern end of the Greater Cursus.
