Woodhenge is a Neolithic Class II henge and timber circle monument within the Stonehenge World Heritage Site in Wiltshire, England. It is 2 miles (3.2 km) northeast of Stonehenge, in Durrington parish, just north of the town of Amesbury.
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 or superhenge is sometimes used as a synonym for a henge enclosure. However, 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' ".
Avebury is a Neolithic henge monument containing three stone circles, around the village of Avebury in Wiltshire, in southwest England. One of the best known prehistoric sites in Britain, it contains the largest megalithic stone circle in the world. It is both a tourist attraction and a place of religious importance to contemporary pagans.
Arbor Low is a well-preserved Neolithic henge in the Derbyshire Peak District, England. It lies on a Carboniferous Limestone plateau known as the White Peak area. The monument consists of a stone circle surrounded by earthworks and a ditch.
Durrington Walls is the site of a large Neolithic settlement and later henge enclosure located in the Stonehenge World Heritage Site in England. It lies 2 miles (3.2 km) north-east of Stonehenge in the parish of Durrington, just north of Amesbury in Wiltshire. The henge is the second-largest Late Neolithic palisaded enclosure known in the United Kingdom, after Hindwell in Wales.
The Thornborough Henges are an ancient monument complex that includes the three aligned henges that give the site its name. They are located on a raised plateau above the River Ure near the village of Thornborough in North Yorkshire, England. The site includes many large ancient structures including a cursus, henges, burial grounds and settlements.
Combe Hill is a causewayed enclosure, near Eastbourne in East Sussex, on the northern edge of the South Downs. It consists of an inner circuit of ditches and banks, incomplete where it meets a steep slope on its north side, and the remains of an outer circuit. Causewayed enclosures were built in England from shortly before 3700 BC until at least 3500 BC; they are 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, meeting places, or ritual sites. The historian Hadrian Allcroft included the site in his 1908 book Earthwork of England, and in 1930 E. Cecil Curwen listed it as a possible Neolithic site in a paper which attempted to provide the first list of all the causewayed enclosures in England.
Cairnpapple Hill is a hill with a dominating position in central lowland Scotland with views from coast to coast. It was used and re-used as a major ritual site for around 4000 years, and in its day would have been comparable to better known sites like the Standing Stones of Stenness. The summit lies 312 m above sea level, and is about 2 miles (3 km) north of Bathgate. In the 19th century the site was completely concealed by trees, then in 1947–1948 excavations by Stuart Piggott found a series of ritual monuments from successive prehistoric periods. In 1998, Gordon Barclay re-interpreted the site for Historic Scotland. It is designated a scheduled ancient monument.
Figsbury Ring is an 11.2 hectare biological Site of Special Scientific Interest in Wiltshire, England, notified in 1975. It is owned and managed by the National Trust.
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.
Prehistoric Orkney refers only to the prehistory of the Orkney archipelago of Scotland that begins with human occupation. Although some records referring to Orkney survive that were written during the Roman invasions of Scotland, “prehistory” in northern Scotland is defined as lasting until the start of Scotland's Early Historic Period.
Mellor hill fort is a prehistoric site in North West England, that dates from the British Iron Age—about 800 BC to 100 AD. Situated on a hill in Mellor, Greater Manchester, on the western edge of the Peak District, the hill fort overlooks the Cheshire Plain. Although the settlement was founded during the Iron Age, evidence exists of activity on the site as far back as 8,000 BC; during the Bronze Age the hill may have been an area where funerary practices were performed. Artefacts such as a Bronze Age amber necklace indicate the site was high status and that its residents took part in long-distance trade. The settlement was occupied into the Roman period. After the site was abandoned, probably in the 4th century, it was forgotten until its rediscovery in the 1990s.
Castell Bryn Gwyn is a prehistoric site on the Isle of Anglesey, west of Brynsiencyn. It is a circular clay and gravel bank covered with grass, still some 1.5 metres (5') high and revetted externally by stone walls, which surround a level area some 54 metres (177') in diameter. Its name means "White Hill Castle".
Marden Henge is the largest Neolithic henge enclosure discovered to date in the United Kingdom. The monument is north-east of the village of Marden, Wiltshire, within the Vale of Pewsey and between the World Heritage Sites of Avebury and Stonehenge.
Blewburton Hill is the site of an Iron Age hillfort located in Oxfordshire, in the southeast of England. It was a univallate hillfort. The area is mostly farmland with some small areas of wooded copse to the south and the northeast. The hill fort may have been occupied from the 4th century BC to the 1st century BC, and replaced a small settlement surrounded by a stockade, which is estimated to have been built in the 5th or 6th century BC.
Scratchbury Camp is the site of an Iron Age univallate hillfort on Scratchbury Hill, overlooking the Wylye valley about 1 km northeast of the village of Norton Bavant in Wiltshire, England. The fort covers an area of 37 acres (15 ha) and occupies the summit of the hill on the edge of Salisbury Plain, with its four-sided shape largely following the natural contours of the hill.
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.
Thundersbarrow Hill is an archaeological site in West Sussex, England. It is on a chalk ridge, aligned north-west to south-east, on the South Downs north of Shoreham-by-Sea.
