Orthostat
This article describes several characteristic architectural elements typical of European megalithic (Stone Age) structures. Forecourt In archaeology, a forecourt is the name given to the area in front of certain types of chamber tomb. Forecourts were probably the venue for ritual practices connected with the burial and commemoration of the dead in the past societies that built these types of tombs. In European megalithic architecture, forecourts are curved in plan with the entrance to the tomb at the apex of the open semicircle enclosure that the forecourt creates. The sides were built up by either large upright stones or walls of smaller stones laid atop one another. Some also had paved floors and some had blocking stones erected in front of them to seal the tomb such as at West Kennet Long Barrow. Their shape, which suggests an attempt to focus attention on the tomb itself may mean that they were used ceremonially as a kind of open air auditorium during ceremonies. Excavation ...

Megalithic
A megalith is a large Rock (geology), stone that has been used to construct a prehistoric structure or monument, either alone or together with other stones. More than 35,000 megalithic structures have been identified across Europe, ranging geographically from Sweden in the north to the Mediterranean Sea in the south. The word was first used in 1849 by the British antiquarian Algernon Herbert in reference to Stonehenge and derives from the Ancient Greek words "wikt:μέγας, mega" for great and "wikt:λίθος, lithos" for stone. Most extant megaliths were erected between the Neolithic period (although earlier Mesolithic examples are known) through the Chalcolithic, Chalcolithic period and into the Bronze Age. Types and definitions While "megalith" is often used to describe a single piece of stone, it also can be used to denote one or more rocks hewn in definite shapes for special purposes. It has been used to describe structures built by people from many parts of the wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cairn
A cairn is a human-made pile (or stack) of stones raised for a purpose, usually as a marker or as a burial mound. The word ''cairn'' comes from the (plural ). Cairns have been and are used for a broad variety of purposes. In prehistory, they were raised as markers, as memorials and as burial monuments (some of which Chambered cairn, contained chambers). In the modern era, cairns are often raised as landmarks, especially to mark the summits of mountains, and as Trail blazing, trail markers. They vary in size from small piles of stones to entire artificial hills, and in complexity from loose conical rock piles to elaborate megalithic structures. Cairns may be painted or otherwise decorated, whether for increased visibility or for religious reasons. History Europe The building of cairns for various purposes goes back into prehistory in Eurasia, ranging in size from small rock sculptures to substantial human-made hills of stone (some built on top of larger, natural hills). ...

Circle
A circle is a shape consisting of all point (geometry), points in a plane (mathematics), plane that are at a given distance from a given point, the Centre (geometry), centre. The distance between any point of the circle and the centre is called the radius. The length of a line segment connecting two points on the circle and passing through the centre is called the diameter. A circle bounds a region of the plane called a Disk (mathematics), disc. The circle has been known since before the beginning of recorded history. Natural circles are common, such as the full moon or a slice of round fruit. The circle is the basis for the wheel, which, with related inventions such as gears, makes much of modern machinery possible. In mathematics, the study of the circle has helped inspire the development of geometry, astronomy and calculus.

Henge
A henge can be one of three related types of Neolithic Earthworks (archaeology), 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 (cf. circular rampart). The three henge types (figures in brackets indicate the approximate diameter of the central flat area) 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 Cove (standing stones), coves. Henge monument is sometimes used as a synonym for henge. Henges sometimes, but ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Timber Circle
In archaeology, timber circles are rings of upright wooden posts, built mainly by ancient peoples in the British Isles and North America. They survive only as gapped rings of post-holes, with no evidence they formed walls, making them distinct from palisades. Like stone circles, it is believed their purpose was ritual, ceremonial, and/or astronomical. Sometimes in North America they are referred to as ''woodhenge''. British Isles Timber circles in the British Isles date to the late Neolithic and early Bronze Age. The posts themselves have long since disappeared and the sites are identified from the rings of postholes that they stood in. Aerial photography and geophysical survey have led to the discovery of increasing numbers of the features. Often a postpipe survives in the posthole fill aiding diagnosis. They are usually more than , and up to , in diameter and the posts that constituted them were generally more than wide. Often they consist of at least two rings or ovals o ...

Bronze Age
The Bronze Age () was a historical period characterised principally by the use of bronze tools and the development of complex urban societies, as well as the adoption of writing in some areas. The Bronze Age is the middle principal period of the three-age system, following the Stone Age and preceding the Iron Age. Conceived as a global era, the Bronze Age follows the Neolithic, with a transition period between the two known as the Chalcolithic. The final decades of the Bronze Age in the Mediterranean basin are often characterised as a period of widespread societal collapse known as the Late Bronze Age collapse (), although its severity and scope are debated among scholars. An ancient civilisation is deemed to be part of the Bronze Age if it either produced bronze by smelting its own copper and alloying it with tin, arsenic, or other metals, or traded other items for bronze from producing areas elsewhere. Bronze Age cultures were the first to History of writing, develop writin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neolithic
The Neolithic or New Stone Age (from Ancient Greek, Greek 'new' and 'stone') is an archaeological period, the final division of the Stone Age in Mesopotamia, Asia, Europe and Africa (c. 10,000 BCE to c. 2,000 BCE). It saw the Neolithic Revolution, a wide-ranging set of developments that appear to have arisen independently in several parts of the world. This "Neolithic package" included the History of agriculture, introduction of farming, domestication of animals, and change from a hunter-gatherer lifestyle to one of sedentism, settlement. The term 'Neolithic' was coined by John Lubbock, 1st Baron Avebury, Sir John Lubbock in 1865 as a refinement of the three-age system. The Neolithic began about 12,000 years ago, when farming appeared in the Epipalaeolithic Near East and Mesopotamia, and later in other parts of the world. It lasted in the Near East until the transitional period of the Chalcolithic (Copper Age) from about 6,500 years ago (4500 BCE), marked by the development ...

British Isles
The British Isles are an archipelago in the Atlantic Ocean, North Atlantic Ocean off the north-western coast of continental Europe, consisting of the islands of Great Britain, Ireland, the Isle of Man, the Inner Hebrides, Inner and Outer Hebrides, Outer Hebrides, the Northern Isles (Orkney and Shetland), and over six thousand smaller islands. They have a total area of and a combined population of almost 72 million, and include two sovereign states, the Republic of Ireland (which covers roughly five-sixths of Ireland), and the United Kingdom, United Kingdom of Great Britain and Northern Ireland. The Channel Islands, off the north coast of France, are normally taken to be part of the British Isles, even though geographically they do not form part of the archipelago. Under the UK Interpretation Act 1978, the Channel Islands are clarified as forming part of the British Islands, not to be confused with the British Isles. The oldest rocks are 2.7 billion years old and are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wiltshire
Wiltshire (; abbreviated to Wilts) is a ceremonial county in South West England. It borders Gloucestershire to the north, Oxfordshire to the north-east, Berkshire to the east, Hampshire to the south-east, Dorset to the south, and Somerset to the west. The largest settlement is Swindon, and Trowbridge is the county town. The county has an area of and a population of 720,060. The county is mostly rural, and the centre and south-west are sparsely populated. After Swindon (183,638), the largest settlements are the city of Salisbury (41,820) and the towns of Chippenham (37,548) and Trowbridge (37,169). For local government purposes, the county comprises two unitary authority areas: Swindon and Wiltshire. Undulating chalk downlands characterize much of the county. In the east are Marlborough Downs, which contain Savernake Forest. To the south is the Vale of Pewsey, which separates the downs from Salisbury Plain in the centre of the county. The south-west is also downland, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stone Circle
A stone circle is a ring of megalithic standing stones. Most are found in Northwestern Europe – especially Stone circles in the British Isles and Brittany – and typically date from the Late Neolithic and Early Bronze Age, with most being built between 3300 and 2500 BC. The best known examples include those at the henge monument at Avebury, the Rollright Stones, Castlerigg, and elements within the ring of standing stones at Stonehenge. Scattered examples exist from other parts of Europe. Later, during the Iron Age, stone circles were built in southern Scandinavia. The archetypical stone circle is an uncluttered enclosure, large enough to congregate inside, and composed of megalithic stones. Often similar structures are named 'stone circle', but these names are either historic, or incorrect. Examples of commonly misinterpreted stone circles are ring cairns, burial mounds, and kerb cairns. Although it is often assumed there are thousands of stone circles across the Br ...

Dry Stone Wall
Dry stone, sometimes called drystack or, in Scotland, drystane, is a building method by which structures are constructed from stones without any mortar to bind them together. A certain amount of binding is obtained through the use of carefully selected interlocking stones. Dry stone construction is best known in the context of stone walls, traditionally used for the boundaries of fields and churchyards, or as retaining walls for terracing, but dry stone shelters, houses and other structures also exist. The term tends not to be used for the many historic styles which used precisely-shaped stone, but did not use mortar, for example the Greek temple and Inca architecture. The art of dry stone walling was inscribed in 2018 on the UNESCO representative list of the intangible cultural heritage of humanity, for dry stone walls in countries such as France, Greece, Italy, Slovenia, Croatia, Switzerland and Spain. In 2024, Ireland was added to the list. History Some dry stone wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
