Chamois P1010758mod
The chamois (''Rupicapra rupicapra'') or Alpine chamois is a species of Caprinae, goat-antelope native to mountains in Europe, from west to east, including the Alps, the Dinarides, the Tatra Mountains, Tatra and the Carpathian Mountains, the Balkan Mountains, the Rila–Rhodope Mountains, Rhodope massif, Pindus, the northeastern mountains of Turkey, and the Caucasus. The chamois has also been introduced to the South Island of New Zealand. Some subspecies of chamois are strictly protected in the EU under the European Habitats Directive. Names The English name comes from French language, French . The latter is derived from Gaulish ''camox'' (attested in Latin, 5th century), itself perhaps borrowing from some Alpine language (Raetic language, Raetic, Ligurian (ancient language), Ligurian). The Gaulish form also underlies German language, German , , , Italian language, Italian , Ladin language, Ladin . The usual pronunciation for the animal is or , approximating the French lang ...

Bunker
A bunker is a defensive military fortification designed to protect people and valued materials from falling bombs, artillery, or other attacks. Bunkers are almost always underground, in contrast to blockhouses which are mostly above ground. They were used extensively in World War I, World War II, and the Cold War for weapons facilities, command and control centers, and storage facilities. Bunkers can also be used as protection from tornadoes. Trench bunkers are small concrete structures, partly dug into the ground. Many artillery installations, especially for coastal artillery, have historically been protected by extensive bunker systems. Typical industrial bunkers include mining sites, food storage areas, dumps for materials, data storage, and sometimes living quarters. When a house is purpose-built with a bunker, the normal location is a reinforced below-ground bathroom with fiber-reinforced plastic shells. Bunkers deflect the blast wave from nearby explosions to prevent ear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tunnel
A tunnel is an underground passageway, dug through surrounding soil, earth or rock, and enclosed except for the entrance and exit, commonly at each end. A pipeline is not a tunnel, though some recent tunnels have used immersed tube construction techniques rather than traditional tunnel boring methods. A tunnel may be for foot or vehicular road traffic, for rail traffic, or for a canal. The central portions of a rapid transit network are usually in the tunnel. Some tunnels are used as sewers or aqueducts to supply water for consumption or for hydroelectric stations. Utility tunnels are used for routing steam, chilled water, electrical power or telecommunication cables, as well as connecting buildings for convenient passage of people and equipment. Secret tunnels are built for military purposes, or by civilians for smuggling of weapons, contraband, or people. Special tunnels, such as wildlife crossings, are built to allow wildlife to cross human-made barriers safely. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Smuggling Tunnel
Smuggling tunnels are secret passages used for the smuggling of goods and people. The term is also used where the tunnels are built in response to a siege. Europe Bosnia The Sarajevo Tunnel operated during the Siege of Sarajevo as a passage underneath the no-man's land of the city's (closed) airport, providing a vital smuggling link for the beleaguered city residents. Guns were smuggled into the city and people were smuggled out. After the Bosnian War, the Sarajevo Tunnel Museum was built onto the historic private house whose cellar served as the entrance to Sarajevo Tunnel. ;In popular culture *It features in the British film ''Welcome to Sarajevo'' (1997). *A similar tunnel in an unknown city, probably Belgrade, features in a dark Serbian satire of conflict, '' Underground'' (1995). Germany More than 70 tunnels were used to smuggle people under the Berlin Wall between West Berlin and East Berlin. Ukraine–Slovakia A 700-meter smuggling tunnel with a narrow gaug ...

Rock-cut Tomb
A rock-cut tomb is a burial chamber that is cut into an existing, naturally occurring rock formation, so a type of rock-cut architecture. They are usually cut into a cliff or sloping rock face, but may go downward in fairly flat ground. It was a common form of burial for the wealthy in ancient times in several parts of the world. Important examples are found in Egypt, most notably in the town of Deir el-Medina (Seet Maat), located between the Valley of the Kings and the Valley of the Queens. Other notable clusters include numerous rock-cut tombs in modern Israel, at Naghsh-e Rostam necropolis in Iran, at Myra in Turkey, Petra in modern Jordan, Mada'in Saleh in Saudi Arabia, Sicily ( Pantalica) and Larnaca. Indian rock-cut architecture is very extensive, but does not feature tombs.

Rock Cut Architecture
Rock-cut architecture is the creation of structures, buildings, and sculptures by excavating solid rock where it naturally occurs. Intensely laborious when using ancient tools and methods, rock-cut architecture was presumably combined with quarrying the rock for use elsewhere. Though, in India and China, the terms ''cave'' and ''cavern'' are often applied to this form of man-made architecture, caves and caverns that began in natural form are not considered to be rock-cut architecture even if extensively modified. Although rock-cut structures differ from traditionally built structures in many ways, many rock-cut structures are made to replicate the facade or interior of traditional architectural forms. Interiors were usually carved out by starting at the roof of the planned space and then working downward. This technique prevents stones falling on workers below. The three main uses of rock-cut architecture were temples (like those in India), tombs, and cave dwellings (like those in ...

Fogou
A fogou or fougou (pronounced "foo-goo") is an underground, dry-stone structure found on Iron Age or Romano-British-defended settlement sites in Cornwall. The original purpose of a fogou is uncertain today. Colloquially called , , , giant holts, or holes in various dialects, fogous have similarities with souterrains or earth-houses of northern Europe and particularly Scotland, including Orkney. Fewer than 15 confirmed fogous have been found. Construction Fogous consist of a buried, usually corbelled stone wall, tapering at the top and capped by stone slabs. They were mainly constructed by excavating a sloping trench about wide and deep, lining it with drystone walling as stated, which was battered inwards and roofed with flat slabs; soil from excavation was heaped on top as at Pendeen Vau or incorporated in the rampart of the enclosure as at Halliggye Fogou, Trelowarren.Fox, Aileen (1973).

Dugout (shelter)
A dugout or dug-out, also known as a pit-house or earth lodge, is a shelter for humans or domesticated animals and livestock based on a hole or depression dug into the ground. Dugouts can be fully recessed into the earth, with a flat roof covered by ground, or dug into a hillside. They can also be semi-recessed, with a constructed wood or sod roof standing out. These structures are one of the most ancient types of human housing known to archaeologists, and the same methods have evolved into modern " earth shelter" technology. Dugouts may also be temporary shelters constructed as an aid to specific activities, e.g., concealment and protection during warfare or shelter while hunting.

Dungeon
A dungeon is a room or cell in which prisoners are held, especially underground. Dungeons are generally associated with medieval castles, though their association with torture probably belongs more to the Renaissance period. An oubliette (from french ''oublier'' meaning to ''forget'') or bottle dungeon is a basement room which is accessible only from a hatch or hole (an '' angstloch'') in a high ceiling. Victims in oubliettes were often left to starve and dehydrate to death, making the practice akin to—and some say an actual variety of— immurement. Etymology The word ''dungeon'' comes from French ''donjon'' (also spelled ''dongeon''), which means "keep", the main tower of a castle. The first recorded instance of the word in English was near the beginning of the 14th century when it held the same meaning as ''donjon''. The proper original meaning of "keep" is still in use for academics, although in popular culture it has been largely misused and come to mean a cell or "oubli ...

Basement
A basement or cellar is one or more Storey, floors of a building that are completely or partly below the storey, ground floor. It generally is used as a utility space for a building, where such items as the Furnace (house heating), furnace, water heating, water heater, breaker panel or fuse box, Garage (residential), car park, and air-conditioning system are located; so also are amenities such as the electrical system and cable television distribution point. In cities with high property prices, such as London, basements are often fitted out to a high standard and used as living space. In British English, the word ''basement'' is usually used for underground floors of, for example, department stores. The word is usually used with houses when the space below the ground floor is habitable, with windows and (usually) its own access. The word ''cellar'' applies to the whole underground level or to any large underground room. A ''subcellar'' is a cellar that lies further underneath ...

Underground Living
Underground living refers to living below the ground's surface, whether in natural or manmade caves or structures. Underground dwellings are an alternative to above-ground dwellings for some home seekers, including those who are looking to minimize impact on the environment. Factories and office buildings can benefit from underground facilities for many of the same reasons as underground dwellings such as noise abatement, energy use, and security. Some advantages of underground houses include resistance to severe weather, quiet living space, an unobtrusive presence in the surrounding landscape, and a nearly constant interior temperature due to the natural insulating properties of the surrounding earth. One appeal is the energy efficiency and environmental friendliness of underground dwellings. However, underground living does have certain disadvantages, such as the potential for flooding, which in some cases may require special pumping systems to be installed. It is the pref ...

Cave Dweller
A cave dweller, or troglodyte, is a human being who inhabits a cave or the area beneath the overhanging rocks of a cliff. Prehistory Some prehistoric humans were cave dwellers, but most were not (''see'' ''Homo'' and Human evolution). Such early cave dwellers, and other prehistoric peoples, are also called ''cave men'' (the term also refers to the stereotypical "caveman" stock character type from fiction and popular culture). Despite the name, only a small portion of humanity has ever dwelt in caves: caves are rare across most of the world; most caves are dark, cold, and damp; and other cave inhabitants, such as bears and cave bears, cave lions, and cave hyenas, often made caves inhospitable for people. The Grotte du Vallonnet, a cave in the French Riviera, was used by people approximately one million years ago. Although stone tools and the remains of eaten animals have been found in the cave, there is no indication that people dwelt in it. Since about 750,000 years ago, ...
