Neolithic monuments consisting of two parallel linear banks with external ditches, forming ceremonial avenues which are often closed at both ends by a continuation of the bank and ditch. Over 30 British examples are now known, the longest being the Dorset Cursus in southern England which extends about 9 km across the chalk downlands. The banks of the Dorset Cursus are about 90 m apart and incorporate two long barrows. The other cursus monuments vary greatly in size (typically under 1 km in length and below 45 m in width), but often incorporate or seem related to other Neolithic ritual enclosures (henges, square mortuary enclosures) or funerary monuments.

The term cursus was derived from 18th-century speculation that they might be the remains of racetracks. Modern interpretations tend to favor the idea of processional avenues, perhaps linking up complex ritual landscapes. Excavation suggests that they were built from around 3000 BC onwards (the Dorset Cursus is associated with Peterborough ware); not all were built in one phase – excavations have shown that some have been extended, while others are composed of a series of separately constructed sections.
