Henge
A henge can be one of three related types of Neolithic earthwork. 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:
- 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 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 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 in diameter. Some true henges are as large as this, but lack evidence of domestic occupation. Mega henge, Super-henge or superhenge is sometimes used as a synonym for a henge enclosure. Sometimes the term is used to indicate size alone rather than use, e.g. "Marden henge ... is the least understood of the four British 'superhenges' ".
Etymology
Stonehenge is not a true henge, as its ditch runs outside its bank, although there is a small extant external bank as well.
Forms
Henges may be classified as follows:- Class I henges, which have a single entrance created from a gap in the bank;
- Class II henges which have two entrances, diametrically opposite each other;
- Class III henges, which have four entrances, facing each other in pairs.

Henges often contain evidence of a variety of internal features, including timber or stone circles, pits, or burials, which may pre- or post-date the henge enclosure. A henge should not be confused with a stone circle within it, as henges and stone circles can exist together or separately. At Arbor Low in Derbyshire, all the stones except one are laid flat and do not seem to have been erected, as no stone holes have been found. Elsewhere, often only the stone holes remain to indicate a former circle.
Some of the best-known henges are at:
- Avebury, about north of Stonehenge on Salisbury Plain, in Wiltshire
- Knowlton Circles, henge complex in Dorset
- Maumbury Rings in Dorset
- Mayburgh Henge in Cumbria
- The Ring of Brodgar in Orkney
- Thornborough Henges complex in Yorkshire

Examples of such ritual landscapes are:
- Balfarg in Fife, Scotland
- Dunragit archaeological excavation site in Wigtownshire
- Heart of Neolithic Orkney, the UNESCO World Heritage Site on the Mainland, one of the islands of Orkney, Scotland
- Stonehenge, Avebury and Associated Sites, the UNESCO World Heritage Site located in Wiltshire, England
- already mentioned: Arbor Low, Knowlton Circles, Stanton Drew stone circles, and Thornborough Henges
- At Avebury, at least two very disturbed inhumations were found in the central area
- Cairnpapple and North Mains both had some burials that pre-date the henges, as well others that post-date them
- At King Arthur's Round Table, Cumbria, a cremation trench lay within the monument
- At Woodhenge, a central burial of a child was interpreted by its excavators as a dedicatory offering
- At Maxey, two cremation pit circles in the southern half of the henge, burials was also present within this monument
Origin and distribution
Concentrations of henges occur over much of Britain. Orkney and Wessex have both been suggested as the original provenance of the monument type; however, others remain unconvinced. Unlike earlier enclosure monuments, henges were not usually built on hilltops but on low-lying ground, often close to watercourses and good agricultural land.
Some scholars, such as the editors of the 1982 edition of the Penguin Dictionary of Archaeology, have claimed that henges are unique to the British Isles. They state that similar, much earlier, circles on the European continent, such as Goseck circle, and later ones such as Goloring are not proper "henges". But The Penguin Archaeological Guide does not comment on geographical locations for henges.

Julian Cope, in The Megalithic European, proposes that the henge was a regional development from the Europe-wide causewayed enclosure. He notes it appeared following a cultural upheaval in around 3000 BC, which inspired the peoples of Neolithic Europe to develop more independently. He notes the rondel enclosures of Bavaria's Isar Valley, which according to investigations by the German archaeologist R. A. Maier, "drew comparisons with the henge monuments and causewayed enclosures of the British Isles." Although still with a multiple-causewayed ditch and entrances at cardinal points, the roundels are described by John Hodgson as not being positioned with defensive aims in mind. The largest, at Kothingeichendorf, appeared to be "midway between a henge and a causewayed enclosure".
Alasdair Whittle also views the development of the henge as a regional variation within a European tradition that included a variety of ditched enclosures. He notes that henges and the grooved ware pottery often found at them are two examples of the British Neolithic not found on the Continent. Caroline Malone also says that henges were not built in the rest of Western Europe, but they developed from a broader tradition of enclosure to become "a phenomenon of the British Isles, a native tradition with sophisticated architecture and calendrical functions."
Interpretation
Henges may have been used for rituals or astronomical observation rather than day-to-day activity. That their ditches are located inside their banks indicates that they were not used for defence, and that the barrier of the earthworks was more likely symbolic than functional. Following arguments presented for Irish Iron Age enclosures, Barclay suggested that they are 'defensive': that the ditch and bank face something 'dangerous' inside the enclosure. He has also suggested that the considerable range of elements surrounded by the earthworks, and the very long date range, are because henges were designed mainly to enclose pre-existing ceremonial sites that were seen as 'ritually charged' and therefore dangerous to people. It has been conjectured that whatever took place inside the enclosures was intended to be separate from the outside world and perhaps known only to select individuals or groups.The alignment of henges is a contentious issue. Popular belief is that their entrances point towards certain heavenly bodies. But henge orientation is highly variable and may have been determined more by local topography than by desire for symbolic orientation. Statistical analysis showed that Class I henges have a slight tendency to have an entrance set in the north or north-east quarter. Class II henges generally have their axes aligned approximately south-east to north-west or north-east to south-west.
It has been suggested that the stone and timber structures sometimes built inside henges were used as solar declinometers to measure the position of the rising or setting sun. These structures do not appear in all henges; and when they do, often they are considerably more recent than the henges. Thus, they are not necessarily connected with the henge's original function. It has been conjectured that the henges would have been used to synchronize a calendar to the solar cycle for purposes of planting crops or timing religious rituals. Some henges have poles, stones or entrances that indicate the position of the rising or setting sun during the equinoxes and solstices, while others appear to frame certain constellations. Additionally, many are placed so that nearby hills either mark or do not interfere with such observations. Finally, some henges appear to be placed at particular latitudes. For example, a number are placed at a latitude of 55 degrees north, where the same two markers can indicate the rising and setting sun for both the spring and autumn equinoxes. But as henges are present from the extreme north to the extreme south of Britain, their latitude could not have been of great importance.
Formalisation is commonly attributed to henges: indications of the builders' concerns to control the arrival at, entrance into, and movement within the enclosures. This was achieved by placing flanking stones or avenues at the entrances of some henges, or by dividing the internal space with timber circles. While some henges were the first monuments to be built in their areas, others were added to already important landscapes, especially the larger examples.
The concentric nature of many of the internal features, such as the five rings of postholes at Balfarg or the six at Woodhenge, may represent a finer distinction than the inside-out differences suggested by henge earthworks. The ordering of space and the circular movement suggested by the sometimes densely packed internal features indicates a sophisticated degree of spatial understanding.
