Dorset Cursus

The Dorset Cursus is a Neolithic earthwork that stretches for ten kilometres across the chalk downland of Cranborne Chase in east Dorset. It is the largest example of its kind in Britain, more than three times longer than the Great Cursus near Stonehenge. The monument consists of two parallel banks with external ditches, built by Neolithic people around 3300 BCE. Little remains above ground today, but aerial photographs reveal its course as cropmarks and soil marks. A few stretches of bank survive, most clearly at the southwestern terminal on Thickthorn Down. Long barrows from the same period lie near or on the Cursus, helping to trace its route across the landscape. Archaeologists believe the Cursus served a religious or ceremonial purpose, though its exact use remains uncertain. The banks were built in two phases: first the Gussage Cursus from Thickthorn Down to Bottlebush Down, then the Pentridge Cursus extending northeast to Martin Down. The earthwork follows a series of straight sections with small changes in direction, ignoring natural features like ridges and valleys. One notable alignment marks the midwinter sunset from Bottlebush Down over a long barrow on Gussage Down. Later peoples, including Bronze Age communities and Roman engineers, reused parts of the landscape around the Cursus. Visitors can still see traces of the earthwork in a few places. On Oakley Down, a surviving bank runs past a long barrow within Salisbury Plantation. A 250-metre stretch of bank remains on Bottlebush Down, visible from the B3081 road. The best-preserved section is at the southwestern terminal on Thickthorn Down, where the bank stands near its original height. The route crosses gentle ridges and shallow valleys, offering views over Cranborne Chase. Nearby long barrows and Bronze Age cemeteries add to the sense of a ritual landscape shaped over millennia.
