A henge loosely describes 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 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 south-west 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.
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.
Bryn Celli Ddu is a prehistoric site on the Welsh island of Anglesey located near Llanddaniel Fab. Its name means 'the mound in the dark grove'. It was archaeologically excavated between 1928 and 1929. Visitors can get inside the mound through a stone passage to the burial chamber, and it is the centrepiece of a major Neolithic Scheduled Monument in the care of Cadw. The presence of a mysterious pillar within the burial chamber, the reproduction of the 'Pattern Stone', carved with sinuous serpentine designs, and the fact that the site was once a henge with a stone circle, and may have been used to plot the date of the summer solstice have all attracted much interest.
Prehistoric Wales in terms of human settlements covers the period from about 230,000 years ago, the date attributed to the earliest human remains found in what is now Wales, to the year AD 48 when the Roman army began a military campaign against one of the Welsh tribes. Traditionally, historians have believed that successive waves of immigrants brought different cultures into the area, largely replacing the previous inhabitants, with the last wave of immigrants being the Celts. However, studies of population genetics now suggest that this may not be true, and that immigration was on a smaller scale.
The Bull Ring is a Class II henge that was built in the late Neolithic period near Dove Holes in Derbyshire, England.
The Holyhead Mountain Hut Circles named in Welsh: Tŷ Mawr / Cytiau'r Gwyddelod, literally meaning Big house or "Irishmen's Huts". are the remains of a group of Celtic Iron Age huts near Trearddur on Holy Island, Anglesey, Wales. The site is under the care of Cadw and can be visited all year round. The construction of these huts is very similar to those at Din Lligwy, having thick stone walls.
Llandygái is a small village and community on the A5 road between Bangor and Tal-y-bont in Gwynedd, Wales. It affords a view of the nearby Carneddau mountain range. The population of the community taken at the 2011 Census was 2,487. Llandygái community includes nearby Tregarth and Mynydd Llandygái and also the pass of Nant Ffrancon.
Lligwy Burial Chamber is a Neolithic burial chamber in Lligwy, near the east coast of Anglesey, Wales, United Kingdom. It consists of a circle of upright stones, made into a low chamber by a very large roof slab estimated at 25 tonnes. Excavation in 1909 found the remains of some 15 to 30 people, and pottery suggesting a late Neolithic date. Close to the village of Moelfre, the site is within a few metres of the road, where there is room to leave a single car for short periods.
Ferrybridge Henge is a Neolithic henge near Ferrybridge, West Yorkshire. It is close to the A1 and M62 and Ferrybridge power station. Ferrybridge Henge is the furthest south of Yorkshire's henges, and is the only one in West Yorkshire. The site is of national importance and is protected from unauthorised change as a Scheduled Ancient Monument; despite this it is under threat from ploughing.
The St Lythans burial chamber is a single stone megalithic dolmen, built around 4,000 BC as part of a chambered long barrow, during the mid Neolithic period, in what is now known as the Vale of Glamorgan, Wales.
Anglesey is an island off the north-west coast of Wales. It forms the bulk of the county known as the Isle of Anglesey, which also includes Holy Island and some islets and skerries. The county borders Gwynedd across the Menai Strait to the southeast, and is otherwise surrounded by the Irish Sea. Holyhead is the largest town, and the administrative centre is Llangefni. The county is part of the preserved county of Gwynedd.
Caer Lêb is a Roman and mediaeval site on the Welsh island of Anglesey, west of Brynsiencyn. Its name means "Leaven Castle". It is a low-lying site near the Afon Braint with a double row of pentangular banks and marshy ditches. The original entrance was on the east, other gaps are modern and caused by animals. Based on the excavation of a similar site elsewhere on Anglesey, it may date from the 2nd century BCE.
Llanfechell is a village in Anglesey, Wales. It is the largest of several small villages and dispersed settlements that make up Mechell Community Council area. It is 11 miles (18 km) east of Holyhead, and 5.6 miles (9 km) west of Amlwch, in the north of the island.
The Bryn Gwyn Stones or Bryn Gwyn Standing Stones are neolithic stones in Brynsiencyn on Anglesey.
Parciau hill fort is a hill fort on the Welsh island of Anglesey. It stands on the summit of Bryn Ddiôl, whose name means "trackless hill".
The archaeology of Wales is the study of human occupation within the country of Wales which has been occupied by modern humans since 225,000 BCE, with continuous occupation from 9,000 BCE. Analysis of the sites, artefacts and other archaeological data within Wales details its complex social landscape and evolution from Prehistoric times to the Industrial period. This study is undertaken by academic institutions, consultancies, charities as well as government organisations.
