Stonehenge Back Wide
Stonehenge is a prehistoric megalithic structure on Salisbury Plain in Wiltshire, England, west of Amesbury. It consists of an outer ring of vertical sarsen standing stones, each around high, wide, and weighing around 25 tons, topped by connecting horizontal lintel stones, held in place with mortise and tenon joints, a feature unique among contemporary monuments. 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 and sunset on the winter 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'' (burial mounds). Stonehenge was constructed in several phases beginning about 3100 BC and continuing until about 1600 BC. The famous circle of large sarsen stones were placed between 2600 BC and ...

West Amesbury
West is one of the four cardinal directions or points of the compass. It is the opposite direction from east and is the direction in which the Sun sets on the Earth. Etymology The word "west" is a Germanic word passed into some Romance languages (''ouest'' in French, ''oest'' in Catalan, ''ovest'' in Italian, ''vest'' in Romanian, ''oeste'' in Spanish and Portuguese). As in other languages, the word formation stems from the fact that west is the direction of the setting sun in the evening: 'west' derives from the Indo-European root ''*wes'' reduced from ''*wes-pero'' 'evening, night', cognate with Ancient Greek ἕσπερος hesperos 'evening; evening star; western' and Latin vesper 'evening; west'. Examples of the same formation in other languages include Latin occidens 'west' from occidō 'to go down, to set' and Hebrew מַעֲרָב (maarav) 'west' from עֶרֶב (erev) 'evening'. West is sometimes abbreviated as W. Navigation To go west using a compass for navigati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sarsen
Sarsen stones are silicification, silicified sandstone blocks found extensively across southern England on the Salisbury Plain and the Marlborough Downs in Wiltshire; in Kent; and in smaller quantities in Berkshire, Essex, Oxfordshire, Dorset, and Hampshire. Geology Sarsen stones are the post-glacial remains of a cap of Cenozoic silcrete that once covered much of southern England. This is thought to have formed during Neogene to Quaternary weathering by the silicification of Upper Paleocene Lambeth Group sediments, resulting from acid leaching. Etymology There are several potential sources for the word "sarsen." The first is that word "sarsen" is a shortening of "Saracen stone" which arose in the Wiltshire dialect. In the Middle Ages, "Saracen" was a common name for Muslims, and came by extension to be used for anything regarded as non-Christian, whether Muslim or pagan in contrast to Christianity. The second is that "sarsen" is vernacular variation of the Indo-European "sasan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scheduled Monument
In the United Kingdom, a scheduled monument is a nationally important archaeological site or historic building, given protection against unauthorised change. The various pieces of legislation that legally protect heritage assets from damage, visual disturbance, and destruction are grouped under the term "Designation (heritage assets), designation". The protection provided to scheduled monuments is given under the Ancient Monuments and Archaeological Areas Act 1979, which is a different law from that used for listed buildings (which fall within the town and country planning system). A heritage asset is a part of the historic environment that is valued because of its historic, archaeological, architectural or artistic interest. Only some of these are judged to be important enough to have extra legal protection through designation. There are about 20,000 scheduled monuments in England representing about 37,000 heritage assets. Of the tens of thousands of scheduled monuments in the UK ...

Radiocarbon Dating
Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for Chronological dating, determining the age of an object containing organic material by using the properties of carbon-14, radiocarbon, a radioactive Isotopes of carbon, isotope of carbon. The method was developed in the late 1940s at the University of Chicago by Willard Libby. It is based on the fact that radiocarbon () is constantly being created in the Atmosphere of Earth, Earth's atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting combines with atmospheric oxygen to form radioactive carbon dioxide, which is incorporated into plants by photosynthesis; animals then acquire by eating the plants. When the animal or plant dies, it stops exchanging carbon with its environment, and thereafter the amount of it contains begins to decrease as the undergoes radioactive decay. Measuring the amount of in a sample from a dead plant or animal, such as a piece of w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tumuli
A tumulus (: tumuli) is a mound of Soil, earth and Rock (geology), stones raised over a grave or graves. Tumuli are also known as barrows, burial mounds, mounds, howes, or in Siberia and Central Asia as ''kurgans'', and may be found throughout much of the world. A cairn, which is a mound of stones built for various purposes, may also originally have been a tumulus. Tumuli are often categorised according to their external apparent shape. In this respect, a long barrow is a long tumulus, usually constructed on top of several burials, such as passage graves. A round barrow is a round tumulus, also commonly constructed on top of burials. The internal structure and architecture of both long and round barrows have a broad range; the categorization only refers to the external apparent shape. The method of may involve a dolmen, a cist, a mortuary enclosure, a mortuary house, or a chamber tomb. Examples of barrows include Duggleby Howe and Maeshowe. Etymology The word ''tumulus'' ...

Bronze Age Britain
Bronze Age Britain is an era of British history that spanned from until . Lasting for approximately 1,700 years, it was preceded by the era of Neolithic Britain and was in turn followed by the period of Iron Age Britain. Being categorised as the Bronze Age, it was marked by the use of copper and then bronze by the prehistoric Britons, who used such metals to fashion tools. Great Britain in the Bronze Age also saw the widespread adoption of agriculture. During the British Bronze Age, large megalithic monuments similar to those from the Late Neolithic continued to be constructed or modified, including such sites as Avebury, Stonehenge, Silbury Hill and Must Farm. That has been described as a time "when elaborate ceremonial practices emerged among some communities of subsistence agriculturalists of western Europe". History Early Bronze Age (EBA), c. 2500–1500 BC There is no clear consensus on the date for the beginning of the Bronze Age in Great Britain and Ireland. Some ...

Neolithic British Isles
The Neolithic period in the British Isles lasted from 4100 to 2,500 Before Christ, BC. Constituting the final stage of the Stone Age in the region, it was preceded by the Mesolithic and followed by the Bronze Age Britain, Bronze Age. During the Mesolithic period, the inhabitants of the British Isles had been hunter-gatherers. Around 4000 BC, migrants began arriving from Central Europe. These migrants brought new ideas, leading to a radical transformation of society and landscape that has been called the Neolithic Revolution. The Neolithic period in the British Isles was characterised by the adoption of agriculture and sedentism, sedentary living. To make room for the new farmland, the early agricultural communities undertook mass deforestation across the islands, which dramatically and permanently transformed the landscape. At the same time, new types of stone tools requiring more skill began to be produced, and new technologies included polishing. Although the earliest indis ...

Earthwork (archaeology)
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. Types There are two broad categories of archaeological earthwork: positive features where earth is built up above the previous ground level, and negative features which are cut into the landscape. Beyond this, earthworks of interest to archaeologists include hill forts, henges, mounds, platform mounds, effigy mounds, enclosures, long barrows, tumuli, ridge and furrow, mottes, round barrows, and other tombs. * Hill forts, a type of fort made out of mostly earth and other natural materials including sand, straw, and water, were built as early as the late Stone Age and were built more frequently during the Bronze Age and Iron Age as a means of protection. See also Oppidum. * Henge earthworks are those that consist of a flat area of ear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Winter Solstice
The winter solstice, or hibernal solstice, occurs when either of Earth's geographical pole, poles reaches its maximum axial tilt, tilt away from the Sun. This happens twice yearly, once in each hemisphere (Northern Hemisphere, Northern and Southern Hemisphere, Southern). For that hemisphere, the winter solstice is the day with the shortest daytime, period of daylight and longest night of the year, and when the Sun is at its lowest culmination, daily maximum elevation in the sky. Each Polar Circle, polar region experiences polar night, continuous darkness or twilight around its winter solstice. The opposite event is the summer solstice. The winter solstice occurs during the hemisphere's winter. In the Northern Hemisphere, this is the December solstice (December 21 or 22) and in the Southern Hemisphere, this is the June solstice (June 20 or 21). Although the winter solstice itself lasts only a moment, the term also refers to the day on which it occurs. Traditionally, in many Tem ...

Summer Solstice
The summer solstice or estival solstice occurs when one of Earth's poles has its maximum tilt toward the Sun. It happens twice yearly, once in each hemisphere ( Northern and Southern). The summer solstice is the day with the longest period of daylight and shortest night of the year in that hemisphere, when the sun is at its highest position in the sky. At either pole there is continuous daylight at the time of its summer solstice. The opposite event is the winter solstice. The summer solstice occurs during the hemisphere's summer. In the Northern Hemisphere, this is the June solstice (20, 21 or 22 June) and in the Southern Hemisphere, this is the December solstice (20, 21, 22 or 23 of December). Since prehistory, the summer solstice has been a significant time of year in many cultures, and has been marked by festivals and rituals. Traditionally, in temperate regions (especially Europe), the summer solstice is seen as the middle of summer and referred to as midsum ...

Trilithon
A trilithon or trilith is a structure consisting of two large vertical stones (posts) supporting a third stone set horizontally across the top ( lintel). It is commonly used in the context of megalithic monuments. The most famous trilithons are those of Stonehenge in England. The word ''trilithon'' is derived from Greek 'having three stones' (τρι- ''tri-'' 'three' + λίθος ''líthos'' 'stone') and was first used in its modern archaeological sense by William Stukeley. Other famous trilithons include those found in the Megalithic temples of Malta (which like Stonehenge are a UNESCO World Heritage Site), the Osireion in Egypt, and the Haʻamonga ʻa Maui in Tonga, Polynesia. The term is also used to describe the groups of three stones in the Hunebed tombs of the Netherlands.

Bluestone
Bluestone is a cultural or commercial name for a number of natural dimension stone, dimension or building stone varieties, including: * basalt in Victoria (Australia), Victoria, Australia, and in New Zealand * diabase, dolerites in Tasmania, Australia; and in Britain (including Stonehenge) * feldspar, feldspathic sandstone in the US and Canada * limestone in the Shenandoah Valley in the US, from the Hainaut (province), Hainaut quarries in Soignies, Belgium, and from quarries in County Carlow, County Galway and County Kilkenny in Ireland * slate in South Australia It is unrelated to human-made blue brick. Stonehenge The term "bluestone" in Britain is used in a loose sense to cover all of the "foreign", not intrinsic, stones and rock debris at Stonehenge. It is a "convenience" label rather than a geological term, since at least 46 different rock types are represented. One of the most common rocks in the assemblage is known as Preseli spotted dolerite—a chemically altered i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
