Butchers' Tower
The Butchers' Tower ( ro, Turnul Măcelarilor, german: Fleischhauerturm) is one of the nine towers located in the Citadel of Sighişoara, belonging to Mureș County in Romania. The Butcher's Tower was built in late 15th century. Originally, the tower was shaped in an eight-sided prism, but in the 16th century it was rebuilt on a hexagonal plan and was raised with the specific purpose of enlarge the field of view over the small bastion A bastion or bulwark is a structure projecting outward from the curtain wall of a fortification, most commonly angular in shape and positioned at the corners of the fort.

Sighișoara
Sighișoara (; hu, Segesvár ; german: Schäßburg ; Transylvanian Saxon: ''Schäsbrich''; yi, שעסבורג, Shesburg; la, Castrum Sex) is a city on the Târnava Mare River in Mureș County, Romania. Located in the historic region of Transylvania, Sighișoara has a population of 28,102 according to the 2011 census. It is a popular tourist destination for its well-preserved walled old town, which is listed by UNESCO as a World Heritage Site. The city administers seven villages: Angofa, Aurel Vlaicu, Hetiur, Rora, Șoromiclea, Venchi, and Viilor. Sighișoara was part of the Hungarian Kingdom until 1918. History During the 12th century, German craftsmen and merchants known as the Transylvanian Saxons were invited to Transylvania by the King of Hungary to settle and defend the frontier of his realm. The chronicler Krauss lists a Saxon settlement in present-day Sighișoara by 1191. A document of 1280 records a town built on the site of a Roman fort as ''Castrum Sex'' or "six- ...

Mureș County
Mureș County (, ro, Județul Mures, hu, Maros megye) is a county ('' județ'') of Romania, in the historical region of Transylvania, with the administrative centre in Târgu Mureș. The county was established in 1968, after the administrative reorganization that re-introduced the historical ''judeţ'' (county) system, still used today. This reform eliminated the previous Mureș-Magyar Autonomous Region, which had been created in 1952 within the People's Republic of Romania. Mureș County has a vibrant multicultural fabric that includes Hungarian-speaking Székelys and Transylvanian Saxons, with a rich heritage of fortified churches and towns. Name In Hungarian, it is known as ''Maros megye'' (), and in German as ''Kreis Mieresch''. Under Kingdom of Hungary, a county with an similar name (Maros-Torda County, ro, Comitatul Mureş-Turda) was created in 1876. There was a county with the same name under the Kingdom of Romania, and a Mureș-Magyar Autonomous Region (1960–19 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Prism (geometry)
In geometry, a prism is a polyhedron comprising an polygon Base (geometry), base, a second base which is a Translation (geometry), translated copy (rigidly moved without rotation) of the first, and other Face (geometry), faces, necessarily all parallelograms, joining corresponding sides of the two bases. All Cross section (geometry), cross-sections parallel to the bases are translations of the bases. Prisms are named after their bases, e.g. a prism with a pentagonal base is called a pentagonal prism. Prisms are a subclass of prismatoids. Like many basic geometric terms, the word ''prism'' () was first used in Euclid's Elements. Euclid defined the term in Book XI as “a solid figure contained by two opposite, equal and parallel planes, while the rest are parallelograms”. However, this definition has been criticized for not being specific enough in relation to the nature of the bases, which caused confusion among later geometry writers.

Hexagon
In geometry, a hexagon (from Ancient Greek, Greek , , meaning "six", and , , meaning "corner, angle") is a six-sided polygon. The total of the internal angles of any simple polygon, simple (non-self-intersecting) hexagon is 720°. Regular hexagon A ''regular polygon, regular hexagon'' has Schläfli symbol and can also be constructed as a Truncation (geometry), truncated equilateral triangle, t, which alternates two types of edges. A regular hexagon is defined as a hexagon that is both equilateral polygon, equilateral and equiangular polygon, equiangular. It is bicentric polygon, bicentric, meaning that it is both cyclic polygon, cyclic (has a circumscribed circle) and tangential polygon, tangential (has an inscribed circle). The common length of the sides equals the radius of the circumscribed circle or circumcircle, which equals \tfrac times the apothem (radius of the inscribed figure, inscribed circle). All internal angles are 120 degree (angle), degrees. A regular hexago ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bastion
A bastion or bulwark is a structure projecting outward from the curtain wall of a fortification, most commonly angular in shape and positioned at the corners of the fort. The fully developed bastion consists of two faces and two flanks, with fire from the flanks being able to protect the curtain wall and the adjacent bastions. Compared with the medieval fortified towers they replaced, bastion fortifications offered a greater degree of passive resistance and more scope for ranged defence in the age of gunpowder artillery. As military architecture, the bastion is one element in the style of fortification dominant from the mid 16th to mid 19th centuries. Evolution By the middle of the 15th century, artillery pieces had become powerful enough to make the traditional medieval round tower and curtain wall obsolete. This was exemplified by the campaigns of Charles VII of France who reduced the towns and castles held by the English during the latter stages of the Hundred Years War, ...

Arquebus
An arquebus ( ) is a form of long gun that appeared in Europe and the Ottoman Empire during the 15th century. An infantryman armed with an arquebus is called an arquebusier. Although the term ''arquebus'', derived from the Dutch word ''Haakbus'' ("hook gun"), was applied to many different forms of firearms from the 15th to 17th centuries, it originally referred to "a hand-gun with a hook-like projection or lug on its under surface, useful for steadying it against battlements or other objects when firing". These "hook guns" were in their earliest forms of defensive weapons mounted on German city walls in the early 15th century. The addition of a shoulder stock, priming pan, and matchlock mechanism in the late 15th century turned the arquebus into a handheld firearm and also the first firearm equipped with a trigger. The exact dating of the matchlock's appearance is disputed. It could have appeared in the Ottoman Empire as early as 1465 and in Europe a little before 1475. The h ...

Round Shot
A round shot (also called solid shot or simply ball) is a solid spherical projectile without explosive charge, launched from a gun. Its diameter is slightly less than the bore of the barrel from which it is shot. A round shot fired from a large-caliber gun is also called a cannonball. The cast iron cannonball was introduced by a French artillery engineer Samuel J. Besh after 1450; it had the capacity to reduce traditional English castle wall fortifications to rubble. French armories would cast a tubular cannon body in a single piece, and cannonballs took the shape of a sphere initially made from stone material. Advances in gunpowder manufacturing soon led the replacement of stone cannonballs with cast iron ones. Round shot was made in early times from dressed stone, referred to as gunstone (Middle English: ''gunneston''), but by the 17th century, from iron. It was used as the most accurate projectile that could be fired by a smoothbore cannon, used to batter the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gunpowder
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 propellan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
