There are three related types of Neolithic earthwork that are all sometimes loosely called henges. The essential characteristic of all three is that they feature a ring-shaped bank and ditch, with the ditch inside the bank. Because the internal ditches would have served defensive purposes poorly, henges are not considered to have been defensive constructions. The three henge types are as follows, with the figure in brackets being the approximate diameter of the central flat area:
- Henge. The word henge refers to a particular type of earthwork of the Neolithic period, typically consisting of a roughly circular or oval-shaped bank with an internal ditch surrounding a central flat area of more than 20 m (66 ft) in diameter. There is typically little if any evidence of occupation in a henge, although they may contain ritual structures such as stone circles, timber circles and coves. Henge monument is sometimes used as a synonym for henge. Henges sometimes, but by no means always, featured stone or timber circles, and circle henge is sometimes used to describe these structures. The three largest stone circles in Britain are each within a henge. Examples of henges without significant internal monuments are the three henges of Thornborough Henges. Although having given its name to the word henge, Stonehenge is atypical in that the ditch is outside the main earthwork bank.
- Hengiform monument. Like an ordinary henge, except the central flat area is between 5 and 20 m (16–66 ft) in diameter, they comprise a modest earthwork with a fairly wide outer bank. The terms Mini henge or Dorchester henge are sometimes used as synonyms for hengiform monument. An example is the Neolithic site at Wormy Hillock Henge.
- Henge enclosure. A Neolithic ring earthwork with the ditch inside the bank, with the central flat area having abundant evidence of occupation and usually being more than 300 m (980 ft) in diameter. Some true henges are as large as this, but lack evidence of domestic occupation. Super henge is sometimes used as a synonym for a henge enclosure. However, sometimes Super henge is used to indicate size alone rather than use, e.g. "Marden henge ... is the least understood of the four British 'superhenges' ".
A causewayed enclosure is a type of large prehistoric earthwork common to the early Neolithic in Europe. It is an enclosure marked out by ditches and banks, with a number of causeways crossing the ditches. More than 100 examples are recorded in France and 70 in Southern England and Wales, while further sites are known in Scandinavia, Belgium, Germany, Italy, Ireland and Slovakia.
Long barrows are a style of monument constructed across Western Europe in the fifth and fourth millennia BCE, during the Early Neolithic period. Typically constructed from earth and either timber or stone, those using the latter material represent the oldest widespread tradition of stone construction in the world. Around 40,000 long barrows survive today.
The Dorset Cursus is a Neolithic cursus monument that spans across 10 km of the chalk downland of Cranborne Chase in east Dorset, United Kingdom. Its extreme length makes it a notable example of this class of linear earthwork; it is better interpreted as a pair of same-length cursus constructed end to end, with the more southerly cursus pre-dating the northerly one.
Round Loaf is a late-Neolithic or Bronze Age tumulus on Anglezarke Moor in the West Pennine Moors near Chorley in Lancashire, England. The bowl barrow is a scheduled monument considered to be of national importance. It was first scheduled in March 1954. The structure is aligned between Great Hill and Pikestones.
The Stoney Littleton Long Barrow is a Neolithic chambered tomb with multiple burial chambers, located near the village of Wellow in the English county of Somerset. It is an example of the Cotswold-Severn Group and was scheduled as an ancient monument in 1882. It was one of the initial monuments included when the Ancient Monuments Protection Act 1882 became law.
The Bull Ring is a Class II henge that was built in the late Neolithic period near Dove Holes in Derbyshire, England.
In archaeology, earthworks are artificial changes in land level, typically made from piles of artificially placed or sculpted rocks and soil. Earthworks can themselves be archaeological features, or they can show features beneath the surface.
The Stonehenge 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. The cursus, along with adjacent barrows and the nearby 'Lesser Cursus' are part of the National Trust's Stonehenge Landscape property, and is within the Stonehenge and Avebury World Heritage Site.
The Cursus Barrows is the name given to a Neolithic and Bronze Age round barrow cemetery lying mostly south of the western end of the Stonehenge Cursus, in Wiltshire, England. The cemetery contains around 18 barrows scattered along an east-to-west ridge, although some of the mounds are no longer visible. The Cursus Barrows can be seen just north of the route between the Stonehenge Visitor Centre and Stonehenge.
Battlegore Burial Chamber is a Bronze Age burial chamber located in Williton, Somerset. It is composed of three round barrows and possibly a long, chambered barrow. The site was excavated in 1931 by George Gray. The name "Battlegore" comes from this site being attributed to the location of a Danish raid in 918 AD or 988 AD. At least as early as the 14th century, the site was referred to as "Bytelgore", a predecessor of the word "Battlegore". Along with three nearby round barrows it has been scheduled as an ancient monument.
Brane Barrow, or Chapel Euny Barrow, is a Neolithic entrance grave located near the hamlet of Brane, Cornwall, England, UK. It is considered to be one of the smallest and best preserved burial monuments in Britain.
Knap Hill lies on the northern rim of the Vale of Pewsey, in northern Wiltshire, England, about a mile north of the village of Alton Priors. At the top of the hill is a causewayed enclosure, a form of Neolithic earthwork that was constructed in England from about 3700 BC onwards, characterized by the full or partial enclosure of an area with ditches that are interrupted by gaps, or causeways. Their purpose is not known: they may have been settlements, or meeting places, or ritual sites of some kind. The site has been scheduled as an ancient monument.
The Grey Mare and her Colts is a megalithic chambered long barrow located near Abbotsbury in Dorset, England. It was built during the Early and Middle Neolithic periods. The tomb was partially excavated in the early nineteenth century, and was found to contain human bones and several pottery fragments.
Knowlton Circles are a complex of henges and earthworks in Knowlton, Dorset, England. The henge enclosing Knowlton Church is the best known and best preserved, but there are at least two other henges in the vicinity as well as numerous round barrows.
Priddy Nine Barrows Cemetery and Ashen Hill Barrow Cemetery are a collection of round barrows, dating from the Bronze Age, near Priddy in the English county of Somerset. They are designated as ancient monuments.
Beacon Hill, also known as Harting Beacon, is a hillfort on the South Downs, in the county of West Sussex in southern England. The hillfort is located in the parish of Elsted and Treyford, in Chichester District. It is a Scheduled Ancient Monument with a list entry identification number of 1015915. The hilltop enclosure is dated to the Late Bronze Age, from the 8th to 6th centuries BC. The hillfort defences were renewed during the Late Iron Age.
Badshot Lea Long Barrow, also known as Farnham Long Barrow, was an unchambered long barrow located near the village of Badshot Lea in the south-eastern English county of Surrey. It was probably constructed in the fourth millennium BCE, during Britain's Early Neolithic period.
Wor Barrow is a Neolithic long barrow on Cranborne Chase, about 1 mile (1.6 km) east of Sixpenny Handley in Dorset, England. It is a scheduled monument.
