Fortress
A fortification is a military construction or building designed for the defense of territories in warfare, and is also used to establish rule in a region during peacetime. The term is derived from Latin ''fortis'' ("strong") and ''facere'' ("to make"). From very early history to modern times, defensive walls have often been necessary for cities to survive in an ever-changing world of invasion and conquest. Some settlements in the Indus Valley civilization were the first small cities to be fortified. In ancient Greece, large stone walls had been built in Mycenaean Greece, such as the ancient site of Mycenae (famous for the huge stone blocks of its 'cyclopean' walls). A Greek ''Towns of ancient Greece#Military settlements, phrourion'' was a fortified collection of buildings used as a military garrison, and is the equivalent of the ancient Roman, Roman castellum or English language, English fortress. These constructions mainly served the purpose of a watch tower, to guard certa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Castra
In the Roman Republic and the Roman Empire, the Latin word ''castrum'', plural ''castra'', was a military-related term. In Latin usage, the singular form ''castrum'' meant 'fort', while the plural form ''castra'' meant 'camp'. The singular and plural forms could refer in Latin to either a building or plot of land, used as a fortified military base.. Included is a discussion about the typologies of Roman fortifications. In English usage, ''castrum'' commonly translates to "Roman fort", "Roman camp" and "Roman fortress". However, scholastic convention tends to translate ''castrum'' as "fort", "camp", "marching camp" or "fortress". Romans used the term ''castrum'' for different sizes of camps – including large legionary fortresses, smaller forts for cohorts or for auxiliary forces, temporary encampments, and "marching" forts. The diminutive form ''castellum'' was used for fortlets, typically occupied by a detachment of a cohort or a '' centuria''. For a list of known castr ...

Defensive Wall
A defensive wall is a fortification usually used to protect a city, town or other settlement from potential aggressors. The walls can range from simple palisades or earthworks to extensive military fortifications with towers, bastions and gates for access to the city. From ancient to modern times, they were used to enclose settlements. Generally, these are referred to as city walls or town walls, although there were also walls, such as the Great Wall of China, Walls of Benin, Hadrian's Wall, Anastasian Wall, and the Atlantic Wall, which extended far beyond the borders of a city and were used to enclose regions or mark territorial boundaries. In mountainous terrain, defensive walls such as ''letzis'' were used in combination with castles to seal valleys from potential attack. Beyond their defensive utility, many walls also had important symbolic functions representing the status and independence of the communities they embraced. Existing ancient walls are almost always masonry ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Castle
A castle is a type of fortified structure built during the Middle Ages predominantly by the nobility or royalty and by military orders. Scholars debate the scope of the word ''castle'', but usually consider it to be the private fortified residence of a lord or noble. This is distinct from a palace, which is not fortified; from a fortress, which was not always a residence for royalty or nobility; from a ''pleasance'' which was a walled-in residence for nobility, but not adequately fortified; and from a fortified settlement, which was a public defence – though there are many similarities among these types of construction. Use of the term has varied over time and has also been applied to structures such as hill forts and 19th-20th century homes built to resemble castles. Over the approximately 900 years when genuine castles were built, they took on a great many forms with many different features, although some, such as curtain walls, arrowslits, and portcullises, were ...

Hill Fort
A hillfort is a type of earthwork used as a fortified refuge or defended settlement, located to exploit a rise in elevation for defensive advantage. They are typically European and of the Bronze Age or Iron Age. Some were used in the post-Roman period. The fortification usually follows the contours of a hill and consists of one or more lines of earthworks, with stockades or defensive walls, and external ditches. Hillforts developed in the Late Bronze and Early Iron Age, roughly the start of the first millennium BC, and were used in many Celtic areas of central and western Europe until the Roman conquest. Nomenclature The spellings "hill fort", "hill-fort" and "hillfort" are all used in the archaeological literature. The ''Monument Type Thesaurus'' published by the Forum on Information Standards in Heritage lists ''hillfort'' as the preferred term. They all refer to an elevated site with one or more ramparts made of earth, stone and/or wood, with an external ditch. M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cannon
A cannon is a large- caliber gun classified as a type of artillery, which usually launches a projectile using explosive chemical propellant. Gunpowder ("black powder") was the primary propellant before the invention of smokeless powder during the late 19th century. Cannons vary in gauge, effective range, mobility, rate of fire, angle of fire and firepower; different forms of cannon combine and balance these attributes in varying degrees, depending on their intended use on the battlefield. A cannon is a type of heavy artillery weapon. The word ''cannon'' is derived from several languages, in which the original definition can usually be translated as ''tube'', ''cane'', or ''reed''. In the modern era, the term ''cannon'' has fallen into decline, replaced by ''guns'' or ''artillery'', if not a more specific term such as howitzer or mortar, except for high-caliber automatic weapons firing bigger rounds than machine guns, called autocannons. The earliest known depict ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Towns Of Ancient Greece
The archetypical settlement in ancient Greece was the self-governing city state called the ''polis'' ( grc-gre, πόλις), but other types of settlement occurred. Kome A ''kome'' ( grc-gre, κώμη) was typically a village that was also a political unit. The translation is inexact, but according to Thucydides, Sparta, though it was a ''polis,'' resembled four unwalled villages. Similarly, a ''kome'' could be a neighbourhood within a larger ''polis'' or its own rural settlement. Thucydides mused that the ''polis'' had developed from the ''kome.'' Katoikia A ''katoikia'' ( grc-gre, κατοικία) was similar to a ''polis'', typically a military colony, with some municipal institutions, but not those of a full ''polis.'' The word derives from the grc, κατοικέω for "''to inhabit''" (a settlement) and is somewhat similar to the Latin ''civitas''. In the Classical era, there were few ''katoikiai''; however, with the rise of large centralized empires following t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nobility
Nobility is a social class found in many societies that have an aristocracy (class), aristocracy. It is normally ranked immediately below Royal family, royalty. Nobility has often been an Estates of the realm, estate of the realm with many exclusive functions and characteristics. The characteristics associated with nobility may constitute substantial advantages over or relative to non-nobles or simply formal functions (e.g., Order of precedence, precedence), and vary by country and by era. Membership in the nobility, including rights and responsibilities, is typically Hereditary title, hereditary and Patrilinearity, patrilineal. Membership in the nobility has historically been granted by a monarch or government, and acquisition of sufficient power, wealth, ownerships, or royal favour has occasionally enabled commoners to ascend into the nobility. There are often a variety of ranks within the noble class. Legal recognition of nobility has been much more common in monarchies, ...

Roman Legion
The Roman legion ( la, legiō, ) was the largest military unit of the Roman army, composed of 5,200 infantry and 300 equites (cavalry) in the period of the Roman Republic (509 BC–27 BC) and of 5,600 infantry and 200 auxilia in the period of the Roman Empire (27 BC – AD 476). Size The size of a typical legion varied throughout the history of ancient Rome, with complements ranging from 4,200 legionaries and 300 equites (drawn from the wealthier classes – in early Rome all troops provided their own equipment) in the Republican period of Rome (the infantry were split into 10 cohorts each of four maniples of 120 legionaries), to 4,800 legionaries (in 10 cohorts of 6 centuries of 80 legionaries) during Caesar's age, to 5,280 men plus 120 auxiliaries in the Imperial period (split into 10 cohorts, nine of 480 men each, with the first cohort being double-strength at 960 men). It should be noted the above numbers are typical field strengths while "paper strength" was sli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Panorama Castillo San Felipe De Barajas CTG 11 2019 2864
A panorama (formed from Greek language, Greek πᾶν "all" + ὅραμα "view") is any Obtuse angle, wide-angle view or representation of a physical space, whether in painting, drawing, photography, film, seismic images, or 3D modeling. The word was originally coined in the 18th century by the English Irish people, (Irish descent) painter Robert Barker (painter), Robert Barker to describe his panoramic paintings of Edinburgh and London. The motion-picture term Panning (camera), ''panning'' is derived from ''panorama''. A panoramic view is also purposed for multimedia, cross-scale applications to an outline overview (from a distance) along and across repositories. This so-called "cognitive panorama" is a panoramic view over, and a combination of, cognitive spaces used to capture the larger scale. History The device of the panorama existed in painting, particularly in murals, as early as 20 A.D., in those found in Pompeii, as a means of generating an immersive "Panopticism, ...

English Language
English is a West Germanic language of the Indo-European language family, with its earliest forms spoken by the inhabitants of early medieval England. It is named after the Angles, one of the ancient Germanic peoples that migrated to the island of Great Britain. Existing on a dialect continuum with Scots, and then closest related to the Low Saxon and Frisian languages, English is genealogically West Germanic. However, its vocabulary is also distinctively influenced by dialects of France (about 29% of Modern English words) and Latin (also about 29%), plus some grammar and a small amount of core vocabulary influenced by Old Norse (a North Germanic language). Speakers of English are called Anglophones. The earliest forms of English, collectively known as Old English, evolved from a group of West Germanic (Ingvaeonic) dialects brought to Great Britain by Anglo-Saxon settlers in the 5th century and further mutated by Norse-speaking Viking settlers starting in the 8th and 9th ...

Ditch (fortification)
In military engineering, a ditch is an obstacle designed to slow down or break up an attacking force, while a trench is intended to provide cover to the defenders. In military fortifications the side of a ditch farthest from the enemy and closest to the next line of defence is known as the scarp while the side of a ditch closest to the enemy is known as the counterscarp. Uses In early fortifications, ditches were often used in combination with ramparts to slow down the enemy whilst defensive fire could be brought to bear from the relative protection afforded by the rampart and possibly the palisade. In medieval fortification, a ditch was often constructed in front of a defensive wall to hinder mining and escalade activities from an attacker. When filled with water, such a defensive ditch is called a moat. However, moats may also be dry. Later star forts designed by military engineers like Vauban, comprised elaborate networks of ditches and parapets, carefully calculated ...

Black Powder
Gunpowder, also commonly known as black powder to distinguish it from modern smokeless powder, is the earliest known chemical explosive. It consists of a mixture of sulfur, carbon (in the form of charcoal) and potassium nitrate (saltpeter). The sulfur and carbon act as fuels while the saltpeter is an oxidizer. Gunpowder has been widely used as a propellant in firearms, artillery, rocketry, and pyrotechnics, including use as a blasting agent for explosives in quarrying, mining, building pipelines and road building. Gunpowder is classified as a low explosive because of its relatively slow decomposition rate and consequently low brisance. Low explosives deflagrate (i.e., burn at subsonic speeds), whereas high explosives detonate, producing a supersonic shockwave. Ignition of gunpowder packed behind a projectile generates enough pressure to force the shot from the muzzle at high speed, but usually not enough force to rupture the gun barrel. It thus makes a good propellant but is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
