Barnenez Entrance
The Cairn of Barnenez (also: Barnenez Tumulus, Barnenez Mound; in Breton language, Breton ''Karn Barnenez''; in French language, French: ''Cairn de Barnenez'' or ''Tumulus de Barnenez'') is a Neolithic monument located near Plouezoc'h, on the Kernéléhen peninsula in northern Finistère, Brittany (France). It dates to the early Neolithic, about 4800 BC. Along with the Tumulus of Bougon and Locmariaquer megaliths, also located in Great West France, it is one of the earliest megaliths, megalithic monuments in Europe and one of the Oldest buildings in the world#By age, oldest man-made structures in the world. It is also remarkable for the presence of megalithic art. History Dates Radiocarbon dating, Radiocarbon dates indicate that the first phase of the monument was erected between 4850 and 4250 BC, and the second phase between 4450 and 4000 BC. Secondary use Pottery found in and around the monument indicates that it underwent a period of reuse in the Bronze Age, in the 3rd mil ...

Napoleon
Napoleon Bonaparte ; it, Napoleone Bonaparte, ; co, Napulione Buonaparte. (born Napoleone Buonaparte; 15 August 1769 – 5 May 1821), later known by his regnal name Napoleon I, was a French military commander and political leader who rose to prominence during the French Revolution and led successful campaigns during the Revolutionary Wars. He was the ''de facto'' leader of the French Republic as First Consul from 1799 to 1804, then Emperor of the French from 1804 until 1814 and again in 1815. Napoleon's political and cultural legacy endures to this day, as a highly celebrated and controversial leader. He initiated many liberal reforms that have persisted in society, and is considered one of the greatest military commanders in history. His wars and campaigns are studied by militaries all over the world. Between three and six million civilians and soldiers perished in what became known as the Napoleonic Wars. Napoleon was born on the island of Corsica, not long af ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Passage Grave
A passage grave or passage tomb consists of one or more burial chambers covered in earth or with stone, and having a narrow access passage made of large stones. These structures usually date from the Neolithic Age, and are found largely in Western Europe. When covered in earth, a passage grave is a type of burial mound which are found in various forms all over the world. When a passage grave is covered in stone, it is a type of cairn. Construction and design The building of passage graves was normally carried out with megaliths along with smaller stones. The earliest passage tombs seem to take the form of small dolmens, although not all dolmens are passage graves. The passage itself, in a number of notable instances, is aligned in such a way that the sun shines through the passage, into the chamber, at a significant point in the year, often at sunrise on the winter solstice or at sunset on the equinox. Many later passage tombs were constructed at the tops of hills or mountains, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dolmen
A dolmen () or portal tomb is a type of single-chamber megalithic tomb, usually consisting of two or more upright megaliths supporting a large flat horizontal capstone or "table". Most date from the early Neolithic (40003000 BCE) and were sometimes covered with earth or smaller stones to form a tumulus (burial mound). Small pad-stones may be wedged between the cap and supporting stones to achieve a level appearance.Murphy (1997), 43 In many instances, the covering has eroded away, leaving only the stone "skeleton". The Korean Peninsula is home to the world's highest concentration of dolmens,UNESCO World Heritage List. "Gochang, Hwasun and Ganghwa Dolmen Sites." https://whc.unesco.org/en/list/977 including "cemeteries" consisting of 30–100 examples located in close proximity to each other; with over 35,000 dolmens, Korea alone (for unknown reasons) accounts for approximately 40% of the global total. History It remains unclear when, why and by whom the earliest dolmens were mad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Granite
Granite () is a coarse-grained (phaneritic) intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground. It is common in the continental crust of Earth, where it is found in igneous intrusions. These range in size from dikes only a few centimeters across to batholiths exposed over hundreds of square kilometers. Granite is typical of a larger family of ''granitic rocks'', or ''granitoids'', that are composed mostly of coarse-grained quartz and feldspars in varying proportions. These rocks are classified by the relative percentages of quartz, alkali feldspar, and plagioclase (the QAPF classification), with true granite representing granitic rocks rich in quartz and alkali feldspar. Most granitic rocks also contain mica or amphibole minerals, though a few (known as leucogranites) contain almost no dark minerals. Granite is nearly alway ...

Dolerite
Diabase (), also called dolerite () or microgabbro, is a mafic, holocrystalline, subvolcanic rock equivalent to volcanic basalt or plutonic gabbro. Diabase dikes and sills are typically shallow intrusive bodies and often exhibit fine-grained to aphanitic chilled margins which may contain tachylite (dark mafic glass). ''Diabase'' is the preferred name in North America, while ''dolerite'' is the preferred name in the rest of the English-speaking world, where sometimes the name ''diabase'' refers to altered dolerites and basalts. Some geologists prefer to avoid confusion by using the name ''microgabbro''. The name ''diabase'' comes from the French ', and ultimately from the Greek - meaning "act of crossing over, transition". Petrography Diabase normally has a fine but visible texture of euhedral lath-shaped plagioclase crystals (62%) set in a finer matrix of clinopyroxene, typically augite (20–29%), with minor olivine (3% up to 12% in olivine diabase), magnetite (2%), and ...

Morlaix
Morlaix (; br, Montroulez) is a commune in the Finistère department of Brittany in northwestern France. It is a sub-prefecture of the department. Leisure and tourism The old quarter of the town has winding streets of cobbled stones and overhanging houses constructed of stone and timber. Many have religious and secular sculptures on their façades. One of these houses is "la Maison dite de la duchesse Anne", or the "so-called Duchess Anne’s house", which is now a museum, open to the public. This house is said to be one of the oldest in the town. Local legend has it that it derives its name from the fact that the Duchesse Anne of Brittany visited the house during her Tro Breizh pilgrimage. This seems unlikely, though, as construction on the house started in the 1520s and Anne of Brittany died in 1514. ThMuseum of the Jacobinsin Morlaix, housed in a former convent, traces the history of Finistère. Morlaix is a popular location for sea sports enthusiasts with a diverse array ...

Stepped Profile
A stepped profile describes the edge of something that has a series of defined steps. It has applications in architecture, construction, engineering, and geology. Applications Architecture and construction In building design a stepped profile is used to reduce the visual impact of, or airborne noise around a building. A stepped profile is also used to calculate seismic and wind loads in multi-story building design. The spillway from a dam can have a stepped profile, which dissipates energy from the released water. Engineering In engineering, a stepped profile may be used on a bearing surface to reduce friction between the moving parts. Geology A mountain with a stepped profile has a number of denudation terraces caused by erosion. A river with a stepped profile has a step-like variation in its gradient along its length. This may be caused by changes in the height of the underlying bedrock. Notable examples * Altar Mountain, a mountain in Victoria Land, Antarctica * Drapers' Ga ...

Excavation (archaeology)
In archaeology, excavation is the exposure, processing and recording of archaeological remains. An excavation site or "dig" is the area being studied. These locations range from one to several areas at a time during a project and can be conducted over a few weeks to several years. Excavation involves the recovery of several types of data from a site. This data includes artifacts (portable objects made or modified by humans), features (non-portable modifications to the site itself such as post molds, burials, and hearths), ecofacts (evidence of human activity through organic remains such as animal bones, pollen, or charcoal), and archaeological context (relationships among the other types of data).Kelly&Thomas (2011). ''Archaeology: down to earth'' (4th ed.). Belmont, Calif.: Wadsworth, Cengage Learning. Before excavating, the presence or absence of archaeological remains can often be suggested by, non-intrusive remote sensing, such as ground-penetrating radar. Basic informat ...
