Stonehenge is a prehistoric monument on Salisbury Plain in Wiltshire, England, two miles (3 km) west of Amesbury. It consists of an outer ring of vertical sarsen standing stones, each around 13 feet (4.0 m) high, seven feet (2.1 m) wide, and weighing around 25 tons, topped by connecting horizontal lintel stones. Inside is a ring of smaller bluestones. Inside these are free-standing trilithons, two bulkier vertical sarsens joined by one lintel. The whole monument, now ruinous, is aligned towards the sunrise on the summer solstice. The stones are set within earthworks in the middle of the densest complex of Neolithic and Bronze Age monuments in England, including several hundred tumuli.
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' ".
Wayland's Smithy is an Early Neolithic chambered long barrow located near the village of Ashbury in the south-central English county of Oxfordshire. The barrow is believed to have been constructed about 3600 BC by pastoral communities shortly after the introduction of agriculture to the British Isles from continental Europe. Although part of an architectural tradition of long barrow building that was widespread across Neolithic Europe, Wayland's Smithy belongs to a localised regional variant of barrows - found only in south-west of Britain - known as the Severn-Cotswold group. Wayland's Smithy is one of the best surviving examples of this type of barrow.
The Coldrum Long Barrow, also known as the Coldrum Stones and the Adscombe Stones, is a chambered long barrow located near the village of Trottiscliffe in the south-eastern English county of Kent. Probably constructed in the fourth millennium BCE, during Britain's Early Neolithic period, today it survives only in a state of ruin.
The Medway Megaliths, sometimes termed the Kentish Megaliths, are a group of Early Neolithic chambered long barrows and other megalithic monuments located in the lower valley of the River Medway in Kent, South-East England. Constructed from local sarsen stone and soil between the 4th and 3rd millennia BCE, they represent the only known prehistoric megalithic group in eastern England and the most south-easterly group in Britain.
Little Kit's Coty House, also known as Lower Kit's Coty House and the Countless Stones, is a chambered long barrow located near to the village of Aylesford in the southeastern English county of Kent. Constructed circa 4000 BCE, during the Early Neolithic period of British prehistory, today it survives in a ruined state.
Chestnuts Long Barrow, also known as Stony Warren or Long Warren, is a chambered long barrow near the village of Addington in the south-eastern English county of Kent. Probably constructed in the fifth millennium BC, during Britain's Early Neolithic period, today it survives only in a ruined state.
Addington Long Barrow is a chambered long barrow located near the village of Addington in the southeastern English county of Kent. Probably constructed in the fourth millennium BCE, during Britain's Early Neolithic period, today it survives only in a ruined state. Built of earth and about fifty local sarsen megaliths, the long barrow consisted of a sub-rectangular earthen tumulus enclosed by kerb-stones. Collapsed stones on the northeastern end of the chamber probably once formed a stone chamber in which human remains might have been deposited, though none have been discovered.
The Stanton Drew stone circles are just outside the village of Stanton Drew in the English county of Somerset. The largest stone circle is the Great Circle, 113 metres (371 ft) in diameter and the second largest stone circle in Britain ; it is considered to be one of the largest Neolithic monuments to have been built. The date of construction is not known, but is thought to be between 3000 and 2000 BCE, which places it in the Late Neolithic to Early Bronze Age. It was made a scheduled monument in 1982.
Long Meg and Her Daughters is a Neolithic stone circle situated north-east of Penrith near Little Salkeld in Cumbria, North West England. One of around 1,300 stone circles in the British Isles and Brittany, it was constructed as a part of a megalithic tradition that emerged during Neolithic, and continued into the Early Bronze Age. The stone circle is the third widest in England, behind Avebury in Wiltshire, and only slightly smaller than Stanton Drew in Somerset.
The Rollright Stones are a complex of three Neolithic and Bronze Age megalithic monuments near the village of Long Compton, on the borders of Oxfordshire and Warwickshire. Constructed from local oolitic limestone, the three monuments, now known as the King's Men and the Whispering Knights in Oxfordshire and the King Stone in Warwickshire, are distinct in their design and purpose. They were built at different periods in late prehistory. During the period when the three monuments were erected, there was a continuous tradition of ritual behaviour on sacred ground, from the 4th to the 2nd millennium BCE.
The Hurlers is a group of three stone circles in the civil parish of St Cleer, Cornwall, England, UK. The site is half-a-mile (0.8 km) west of the village of Minions on the eastern flank of Bodmin Moor, and approximately four miles (6 km) north of Liskeard.
Swinside, which is also known as Sunkenkirk and Swineshead, is a stone circle lying beside Swinside Fell, part of Black Combe in southern Cumbria, North West England. One of around 1,300 recorded stone circles in the British Isles and Brittany, it was constructed as a part of a megalithic tradition that lasted from 3,300 to 900 BC, during what archaeologists categorise as the Late Neolithic and Early Bronze Ages.
Boscawen-Ûn is a Bronze Age stone circle close to St Buryan in Cornwall, UK. It consists of nineteen upright stones in an ellipse with another, leaning, middle stone just south of the centre. There is a west-facing gap in the circle, which may have formed an entrance. The elliptical circle has diameters 24.9 and 21.9 metres. It is located at grid reference SW412274.
The Trippet stones or Trippet stones circle is a stone circle located on Manor Common in Blisland, 9 kilometres (5.6 mi) north northeast of Bodmin on Bodmin Moor in Cornwall, UK. The Stripple stones are nearby.
The stone circles in the British Isles and Brittany are a megalithic tradition of monuments consisting of standing stones arranged in rings. These were constructed from 3300 to 900 BCE in Britain, Ireland and Brittany. It has been estimated that around 4,000 of these monuments were originally constructed in this part of north-western Europe during this period. Around 1,300 of them are recorded, the others having been destroyed.
Nine Stones Close, also known as the Grey Ladies, is a stone circle on Harthill Moor in Derbyshire in the English East Midlands. It is part of a tradition of stone circle construction that spread throughout much of Britain, Ireland, and Brittany during the Late Neolithic and Early Bronze Ages, over a period between 3300 and 900 BCE. The purpose of the monument is unknown.
The Nine Stones, also known as the Devil's Nine Stones, the Nine Ladies, or Lady Williams and her Dog, is a stone circle located near to the village of Winterbourne Abbas in the southwestern English county of Dorset. Archaeologists believe that it was likely erected during the Bronze Age.
