Fort Du Bruissin
The Fort du Bruissin is a fort in Francheville, France, near the city of Lyon. Built between 1878 and 1881, the fort is part of the Séré de Rivières system of fortifications built in the late 19th century. It has been rehabilitated as a contemporary artists' community. The ''Fort en Jazz'' festival is held there each year.http://www.mairie-francheville69.fr/vc_page38.php page de la mairie sur le fort Concept and design The Fort de Bruissin is located about to the southeast of the center of Lyon. Lyon's original protective ring of forts was built in the 1830s at a distance from the city just beyond the range of the artillery of the era, thus denying a potential attacker the means to bombard Lyon. With the introduction of rifled artillery, the range increased, placing the city once again into jeopardy. In the 1870s a second ring of forts was built farther out to deal with the extended range of artillery. Work on the second ring of eighteen forts was complete by 1893. The F ...

Fortifications Of Lyon
The ceintures de Lyon ('Belts of Lyon') were a series of fortifications built between 1830 and 1890 around the city of Lyon, France, to protect the city from foreign invasion. The belts comprised two defensive barriers that included forts, lunettes, ramparts, batteries, and other defensive structures. Many of these structures proved to be ineffective in war due to advancement in weapon technology and the evolution of attack strategies at the time. Some of the fortifications of the ceintures de Lyon have been destroyed, though many remain today. History After the July Revolution in 1830 and the end of the Bourbon monarchy, the government feared a new war. Austria was seen as the major threat to France at the time, and so protecting the east and south-east borders became a priority. Construction of the first belt In 1830 the maréchal de camp, Hubert Rohault de Fleury, commenced a project designed by military engineer Baron Haxo. With a budget of francs (approximat ...

Séré De Rivières System
The system was named after Raymond Adolphe Séré de Rivières, its originator. The system was an ensemble of fortifications built from 1874 along the frontiers and coasts of France. The fortresses were obsolescent by 1914 but were used during the First World War. Background Following the Franco-Prussian War of 1870–1871, France found itself seriously weakened and isolated from the rest of Europe, menaced by Germany and stung by the loss of Alsace-Lorraine. At the same time as the departure of the last German troops, France created the Defence Committee (), which was active between 1872 and 1888, whose mission was to reorganize the defence of the French frontiers and coasts. It was necessary to compensate for the lost territories of the north-east; to modernise old fortifications, which had been shown to be wanting in the last war and to create new fortifications proof against modern weaponry using new and more powerful explosives. The committee was created by a preside ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fort Du Bruissin01
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 '' phrourion'' was a fortified collection of buildings used as a military garrison, and is the equivalent of the Roman castellum or English fortress. These constructions mainly served the purpose of a watch tower, to guard certain roads, passes, and borders. Though smaller than a real fortress, they acted ...

Lyon
Lyon,, ; Occitan: ''Lion'', hist. ''Lionés'' also spelled in English as Lyons, is the third-largest city and second-largest metropolitan area of France. It is located at the confluence of the rivers Rhône and Saône, to the northwest of the French Alps, southeast of Paris, north of Marseille, southwest of Geneva, northeast of Saint-Étienne. The City of Lyon proper had a population of 522,969 in 2019 within its small municipal territory of , but together with its suburbs and exurbs the Lyon metropolitan area had a population of 2,280,845 that same year, the second most populated in France. Lyon and 58 suburban municipalities have formed since 2015 the Metropolis of Lyon, a directly elected metropolitan authority now in charge of most urban issues, with a population of 1,411,571 in 2019.

Rifling
In firearms, rifling is machining helical grooves into the internal (bore) surface of a gun's barrel for the purpose of exerting torque and thus imparting a spin to a projectile around its longitudinal axis during shooting to stabilize the projectile longitudinally by conservation of angular momentum, improving its aerodynamic stability and accuracy over smoothbore designs. Rifling is characterized by its twist rate, which indicates the distance the rifling takes to complete one full revolution, such as "1 turn in 10 inches" (1:10 inches), "1 turn in 254 mm" ("1:254 mm" or "1:25.4 cm)", or the like. Normally, an experienced shooter can infer the units of measurement from the numbers alone. A shorter distance indicates a faster twist, meaning that for a given velocity the projectile will rotate at a higher spin rate. The combination of length, weight, and shape of a projectile determines the twist rate needed to gyroscopically stabilize it – barrel ...

Revolving Cannon
Rotation, or spin, is the circular movement of an object around a '' central axis''. A two-dimensional rotating object has only one possible central axis and can rotate in either a clockwise or counterclockwise direction. A three-dimensional object has an infinite number of possible central axes and rotational directions. If the rotation axis passes internally through the body's own center of mass, then the body is said to be ''autorotating'' or ''spinning'', and the surface intersection of the axis can be called a ''pole''. A rotation around a completely external axis, e.g. the planet Earth around the Sun, is called ''revolving'' or ''orbiting'', typically when it is produced by gravity, and the ends of the rotation axis can be called the ''orbital poles''. Mathematics Mathematically, a rotation is a rigid body movement which, unlike a translation, keeps a point fixed. This definition applies to rotations within both two and three dimensions (in a plane and in space, r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caponier
A caponier is a type of defensive structure in a fortification. Fire from this point could cover the ditch beyond the curtain wall to deter any attempt to storm the wall. The word originates from the French ', meaning "chicken coop" (a ''capon'' is a castrated male chicken). In some types of bastioned fortifications, the caponier served as a means of access to the outworks, protecting troops from direct fire; they were often roofless. Although they could be used for firing along the ditch, the flanks of the bastions were the main defence of the ditch by fire. In later polygonal forts, caponiers were often roofed, and were not intended as a type of ''covered way'', but as the main way of keeping the ditch clear of the enemy. History Originally the term referred to a covered passageway that traversed the ditch outside the curtain of a fortress. Fire from this point could cover the ditch beyond the curtain wall to deter any attempt to storm the wall. Thus the passageway was equip ...

World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
