Pont Saint-Bénézet
The Pont Saint-Bénézet (; Provençal: ''Pònt de Sant Beneset''), also known as the Pont d'Avignon (), was a medieval bridge across the Rhône in the town of Avignon, in southern France. Only four arches survive. A wooden bridge spanning the Rhône between Villeneuve-lès-Avignon and Avignon was built between 1177 and 1185. This early bridge was destroyed forty years later in 1226 during the Albigensian Crusade when Louis VIII of France laid siege to Avignon. Beginning in 1234 the bridge was rebuilt with 22 stone arches. The stone bridge was about in length and only in width, including the parapets at the sides. The bridge was abandoned in the mid-17th century as the arches tended to collapse each time the Rhône flooded making it very expensive to maintain. Four arches and the gatehouse at the Avignon end of the bridge have survived. The Chapel of Saint Nicholas which sits on the second pier of the bridge, was constructed in the second half of 12th century but has si ...

Braun Hogenberg Avignon 1575 Crop Bridge
Braun is a common surname, originating from the German word for the color brown. The name is the 22nd most common family name in Germany. Many German emigrants to the United States also changed their name to ''Brown'' (''see Brown (surname)''). In German, ''Braun'' is pronounced , except for the "r" equal to the English word "brown". In English, it is often pronounced as "brawn", as in 'Carol Moseley Braun'. Pronunciation is an individual preference and is hard to guess unless one is in a position to hear the person's name spoken.

Bridge Scour
Bridge scour is the removal of sediment such as sand and gravel from around bridge abutments or piers. Hydrodynamic scour, caused by fast flowing water, can carve out ''scour holes'', compromising the integrity of a structure. In the United States, bridge scour is one of the three main causes of bridge failure (the others being collision and overloading). It has been estimated that 60% of all bridge failures result from scour and other hydraulic-related causes.Mark N.

Starling (architecture)
In architecture, a starling (or sterling) is a defensive bulwark, usually built with pilings or bricks, surrounding the supports (or piers) of a bridge or similar construction. Starlings may be shaped to ease the flow of the water around the bridge, reducing the damage caused by erosion or collisions with flood-borne debris, and may also form an important part of the structure of the bridge, spreading the weight of the piers. The term cutwater is used for such a structure shaped with water flow in mind, as a pier or starling with a diamond point. A starkwater is a bulwark against ice floes. Depending on their shape and location, some starlings may accumulate river debris, mud and other objects, potentially creating navigational hazards or hindering downstream water flow. Shape Starlings may form part of a buttress for the vertical load of the bridge piers, and for that purpose would typically be symmetrical. Examples such as at the Old Wye Bridge, Chepstow are on lower stretc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Circular Segment
In geometry, a circular segment (symbol: ), also known as a disk segment, is a region of a disk which is "cut off" from the rest of the disk by a secant or a chord. More formally, a circular segment is a region of two-dimensional space that is bounded by a circular arc (of less than π radians by convention) and by the circular chord connecting the endpoints of the arc. Formulae Let ''R'' be the radius of the arc which forms part of the perimeter of the segment, ''θ'' the central angle subtending the arc in radians, ''c'' the chord length, ''s'' the arc length, ''h'' the sagitta (height) of the segment, ''d'' the apothem of the segment, and ''a'' the area of the segment. Usually, chord length and height are given or measured, and sometimes the arc length as part of the perimeter, and the unknowns are area and sometimes arc length. These can't be calculated simply from chord length and height, so two intermediate quantities, the radius and central angle are usually calcula ...

Radiocarbon Dating
Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon. The method was developed in the late 1940s at the University of Chicago by Willard Libby. It is based on the fact that radiocarbon () is constantly being created in the Earth's atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting combines with atmospheric oxygen to form radioactive carbon dioxide, which is incorporated into plants by photosynthesis; animals then acquire by eating the plants. When the animal or plant dies, it stops exchanging carbon with its environment, and thereafter the amount of it contains begins to decrease as the undergoes radioactive decay. Measuring the amount of in a sample from a dead plant or animal, such as a piece of wood or a fragment of bone, provides information that can be used to calc ...

Louis XI Of France
Louis XI (3 July 1423 – 30 August 1483), called "Louis the Prudent" (french: le Prudent), was King of France from 1461 to 1483. He succeeded his father, Charles VII. Louis entered into open rebellion against his father in a short-lived revolt known as the Praguerie in 1440. The king forgave his rebellious vassals, including Louis, to whom he entrusted the management of the Dauphiné, then a province in southeastern France. Louis's ceaseless intrigues, however, led his father to banish him from court. From the Dauphiné, Louis led his own political establishment and married Charlotte of Savoy, daughter of Louis, Duke of Savoy, against the will of his father. Charles VII sent an army to compel his son to his will, but Louis fled to Burgundy, where he was hosted by Philip the Good, the Duke of Burgundy, Charles' greatest enemy. When Charles VII died in 1461, Louis left the Burgundian court to take possession of his kingdom. His taste for intrigue and his intense diplomatic ac ...

Pope Clement VI
Pope Clement VI ( la, Clemens VI; 1291 – 6 December 1352), born Pierre Roger, was head of the Catholic Church from 7 May 1342 to his death in December 1352. He was the fourth Avignon pope. Clement reigned during the first visitation of the Black Death (1348–1350), during which he granted remission of sins to all who died of the plague. Roger steadfastly resisted temporal encroachments on the Church's ecclesiastical jurisdiction and, as Clement VI, entrenched French dominance of the Church and opened its coffers to enhance the regal splendour of the Papacy. He recruited composers and music theorists for his court, including figures associated with the then-innovative Ars Nova style of France and the Low Countries. Early life Birth and family Pierre Roger (also spelled Rogier and Rosiers) was born in the château of Maumont, today part of the commune of Rosiers-d'Égletons, Corrèze, in Limousin, France, the son of the lord of Maumont-Rosiers-d'Égletons.

Siege Of Avignon (1226)
The siege of Avignon was the principal military action of the Albigensian Crusade of 1226. King Louis VIII of France besieged the town of Avignon, which lay within the Holy Roman Empire, from 10 June until 9 September, when it surrendered on terms. Background Louis VIII assembled the largest army of the Albigensian Crusades at Bourges in May 1226. He advanced to Lyon and then down the Rhône Valley on the left bank (the imperial side), his ultimate goal being the submission of Count Raymond VII of Toulouse, who as Marquis of Provence also held lordship over Avignon. The latter was an autonomous city, governed by a ''podestà'' and consuls on the Italian model. It was wealthy, possessing a full double wall with two large gate towers (named Quiquenparle and Quiquengrogne). Its defences were manned by mercenary soldiers. It had, however, been under an interdict for twelve years for having refused an order of the pope. Louis's plan was to cross back into France at Avignon. Representat ...
