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] |
Führerbunker
The () was an air raid shelter located near the Reich Chancellery in Berlin, Germany. It was part of a subterranean bunker complex constructed in two phases in 1936 and 1944. It was the last of the Führer Headquarters (''Führerhauptquartiere'') used by Adolf Hitler during World War II. Hitler took up residence in the on 16 January 1945, and it became the centre of the Nazi regime until the last week of World War II in Europe. Hitler married Eva Braun there on 29 April 1945, less than 40 hours before they committed suicide. After the war, both the old and new Chancellery buildings were levelled by the Soviet Red Army. The underground complex remained largely undisturbed until 1988–89, despite some attempts at demolition. The excavated sections of the old bunker complex were mostly destroyed during reconstruction of that area of Berlin. The site remained unmarked until 2006, when a small plaque was installed with a schematic diagram. Some corridors of the bunker ...

Bunker (golf)
A hazard is an area of a golf course in the sport of golf which provides a difficult obstacle, which may be of two types: (1) penalty areas such as lakes and rivers; and (2) bunkers. A penalty area was previously referred to as a water hazard. Special rules apply to play balls that fall in a hazard. For example, a player may not touch the ground with their club before playing a ball, not even for a practice swing. A ball in any hazard may be played as it lies without penalty. If it cannot be played from the hazard, the ball may be hit from another location, generally with a penalty of one stroke. The Rules of Golf govern exactly from where the ball may be played outside a hazard. Bunkers (or sand traps) are shallow pits filled with sand and generally incorporating a raised lip or barrier, from which the ball is more difficult to play than from grass. Bunker A bunker is a depression, commonly near the green or fairway, that is usually filled with sand. Playing the ball from ...

Pillbox (military)
A pillbox is a type of blockhouse, or concrete dug-in guard-post, often camouflaged, normally equipped with Loophole_(firearm), loopholes through which defenders can fire weapons. It is in effect a trench warfare , trench firing step, hardened to protect against small-arms fire and grenades, and raised to improve the field of fire. The modern concrete pillbox originated on the Western Front (World War I) , Western Front of World War I, in the Imperial German Army , German Army in 1916. Etymology The origin of the term is disputed. It has been widely assumed to be a jocular reference to the perceived similarity of the fortifications to the Cylinder, cylindrical and hexagonal boxes in which medical pills were once sold; also, the first German concrete pillboxes discovered by the Allies in Belgium were so small and light that they were easily tilted or turned upside down by the nearby explosion of even medium (240mm) shells. However, it seems more likely that it original ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bunker Buster
A bunker buster is a type of munition that is designed to penetrate hardened targets or targets buried deep underground, such as military bunkers. Armor piercing shells Germany Röchling shells were bunker-busting artillery shells, developed by the German engineer August Coenders, based on the theory of increasing sectional density to improve penetration. They were tested in 1942 and 1943 against the Belgian Fort d'Aubin-Neufchâteau. Aircraft delivered bombs World War II Germany In World War II the Luftwaffe developed a series of unguided rocket-propelled armor-piercing bombs for use against shipping and fortifications. United Kingdom In World War II, the British designer Barnes Wallis, already famous for inventing the bouncing bomb, designed two bombs that would become the conceptual predecessors of modern bunker busters: the five tonne Tallboy and the ten tonne Grand Slam. These were "Earthquake" bombs—a concept he had first proposed in 1939. The designs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Augarten Flakturm Wien2008a
The Augarten is a public park of situated in the Leopoldstadt, the second district of Vienna, Austria. It contains the city's oldest Baroque park. In the north-west and north-east it borders (since 1900) on the 20th district, Brigittenau, in the north-east also on the former Wien Nordwestbahnhof, Nordwestbahnhof, from where the North Western Railway made its way to Bohemia, while to the south it faces the so-called ''Karmeliterviertel'' ("Carmelite quarter"), the historical Jewish quarter, followed by the Leopoldstadt. Until 1870 (Vienna Danube regulation), the areas north and east of the Augarten were floodlands mostly uninhabited. The park is designed in the French Baroque style with elaborate flower gardens and impressive shady avenues of chestnut, lime, ash, and maple. Like most fenced public parks and gardens in Vienna it is open only in the daytime: the park's five gates close at sunset (signalled by a siren). The Augarten hosts a variety of facilities such as the ''Wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blockhouse
A blockhouse is a small fortification, usually consisting of one or more rooms with loopholes, allowing its defenders to fire in various directions. It is usually an isolated fort in the form of a single building, serving as a defensive strong point against any enemy that does not possess siege equipment or, in modern times, artillery, air force or cruise missiles. A fortification intended to resist these weapons is more likely to qualify as a fortress or a redoubt, or in modern times, be an underground bunker. However, a blockhouse may also refer to a room within a larger fortification, usually a battery or redoubt. Etymology The term '' blockhouse'' is of uncertain origin, perhaps related to Middle Dutch '' blokhus'' and 18th-century French '' blocus'' (blockade). In ancient Greece Blockhouses existed in ancient Greece, for example the one near Mycenae. Early blockhouses in England Early blockhouses were designed solely to protect a particular area by the use of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hochbunker
Air raid shelters are structures for the protection of non-combatants as well as combatants against enemy attacks from the air. They are similar to bunkers in many regards, although they are not designed to defend against ground attack (but many have been used as defensive structures in such situations). History Pre-WWII Prior to World War II, in 1924, an Air Raid Precautions Committee was set up in the United Kingdom. For years, little progress was made with shelters because of the apparently irreconcilable conflict between the need to send the public underground for shelter and the need to keep them above ground for protection against gas attacks. In 1935, every city in the country was given a document to prepare air raid shelters. In February 1936 the Home Secretary appointed a technical Committee on Structural Precautions against Air Attack. By November 1937, there had only been slow progress, because of a serious lack of data on which to base any design recommenda ...

Coastal Artillery
Coastal artillery is the branch of the armed forces concerned with operating anti-ship artillery or fixed gun batteries in coastal fortifications. From the Middle Ages until World War II, coastal artillery and naval artillery in the form of cannons were highly important to military affairs and generally represented the areas of highest technology and capital cost among materiel. The advent of 20th-century technologies, especially military aviation, naval aviation, jet aircraft, and guided missiles, reduced the primacy of cannons, battleships, and coastal artillery. In countries where coastal artillery has not been disbanded, these forces have acquired amphibious capabilities. In littoral warfare, mobile coastal artillery armed with surface-to-surface missiles can still be used to deny the use of sea lanes. It was long held as a rule of thumb that one shore-based gun equaled three naval guns of the same caliber, due to the steadiness of the coastal gun which allowed ...

Dugout (military)
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.

Coal Bunker
A coal bin, coal store or coal bunker is a storage container for coal awaiting use or transportation. This can be either in domestic, commercial or industrial premises, or on a ship or locomotive tender, or at a coal mine or processing plant. Domestic coal bunkers are associated with the use of coal in open fires or for solid-fuel central heating. Free-standing bunkers were commonly made of wood or concrete and are currently sold in materials including plastic or galvanised metal. Coal bins or bunkers could also form an outhouse or be partly or fully underground. Coal bins form or formed part of industrial plants, and were found on steam ships. See also * Tender (rail) A tender is a special rail vehicle hauled by a steam locomotive containing its fuel (wood, coal, oil or torrefied biomass) and water. Steam locomotives consume large quantities of water compared to the quantity of fuel, so their tenders are ... References {{architecture-stub Semi-subterranean s ...
