Grand Arvou Bridge
The Bridge of Grand Arvou The Petit Arvou The Bridge of Gran Arvou (Italian: ''Ponte acquedotto di Grand Arvou'', French: ''Pont aqueduc du Grand Arvou'') is an aqueduct-bridge in the ''frazione'' Porossan of Aosta, north-western Italy. It span the Rû Prévôt irrigation canal, and includes a large corridor covered by flagstones. Another aqueduct-bridge, the Petit Arvou, is located a few meters downstream. History In the late 13th-early 14th century, there was a series of programs aiming to improve the irrigation level in Aosta Valley, due to increased demand of animal husbandry. One of these was the construction of a canal, the Rû Prévôt, by will of Henry of Quart, provost (hence the name) of the Aosta Cathedral. This included also the pair of bridge-aqueducts which are now visible. The income of the canal exploitation was later acquired by the Dukes (later Kings) of Savoy. In the 20th century, the canal was mostly (11,9 km out of 12) channeled into pipes. Descrip ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Provost (religion)
A provost is a senior official in a number of Christian Churches. Historical development The word ''praepositus'' (Latin: "set over", from ''praeponere'', "to place in front") was originally applied to any ecclesiastical ruler or dignitary. It was soon more specifically applied to the immediate subordinate to the abbot of a monastery, or to the superior of a single cell, and it was defined as such in the Rule of St Benedict. The dean (''decanus'') was a similarly ranked official. Chrodegang of Metz adopted this usage from the Benedictines when he introduced the monastic organization of canon-law colleges, especially cathedral capitular colleges. The provostship (''praepositura'') was normally held by the archdeacon, while the office of dean was held by the archpriest. In many colleges, the temporal duties of the archdeacons made it impossible for them to fulfil those of the provostship, and the headship of the chapter thus fell to the dean. The title became ''prevost'' in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bridges In Aosta Valley
A bridge is a structure built to span a physical obstacle (such as a body of water, valley, road, or rail) without blocking the way underneath. It is constructed for the purpose of providing passage over the obstacle, which is usually something that is otherwise difficult or impossible to cross. There are many different designs of bridges, each serving a particular purpose and applicable to different situations. Designs of bridges vary depending on factors such as the function of the bridge, the nature of the terrain where the bridge is constructed and anchored, and the material used to make it, and the funds available to build it. The earliest bridges were likely made with fallen trees and stepping stones. The Neolithic people built boardwalk bridges across marshland. The Arkadiko Bridge (dating from the 13th century BC, in the Peloponnese) is one of the oldest arch bridges still in existence and use.

Trapezoid
A quadrilateral with at least one pair of parallel sides is called a trapezoid () in American and Canadian English. In British and other forms of English, it is called a trapezium (). A trapezoid is necessarily a Convex polygon, convex quadrilateral in Euclidean geometry. The parallel sides are called the ''bases'' of the trapezoid. The other two sides are called the ''legs'' (or the ''lateral sides'') if they are not parallel; otherwise, the trapezoid is a parallelogram, and there are two pairs of bases). A ''scalene trapezoid'' is a trapezoid with no sides of equal measure, in contrast with the #Special cases, special cases below. Etymology and ''trapezium'' versus ''trapezoid'' Ancient Greek mathematician Euclid defined five types of quadrilateral, of which four had two sets of parallel sides (known in English as square, rectangle, rhombus and rhomboid) and the last did not have two sets of parallel sides – a τραπέζια (''trapezia'' literally "a table", itself fr ...

Mortar (masonry)
Mortar is a workable paste which hardens to bind building blocks such as stones, bricks, and concrete masonry units, to fill and seal the irregular gaps between them, spread the weight of them evenly, and sometimes to add decorative colors or patterns to masonry walls. In its broadest sense, mortar includes pitch, asphalt, and soft mud or clay, as those used between mud bricks, as well as cement mortar. The word "mortar" comes from Old French ''mortier'', "builder's mortar, plaster; bowl for mixing." (13c.). Cement mortar becomes hard when it cures, resulting in a rigid aggregate structure; however, the mortar functions as a weaker component than the building blocks and serves as the sacrificial element in the masonry, because mortar is easier and less expensive to repair than the building blocks. Bricklayers typically make mortars using a mixture of sand, a binder, and water. The most common binder since the early 20th century is Portland cement, but the ancient binder lim ...

Arch Bridge
An arch bridge is a bridge with abutments at each end shaped as a curved arch. Arch bridges work by transferring the weight of the bridge and its loads partially into a horizontal thrust restrained by the abutments at either side. A viaduct (a long bridge) may be made from a series of arches, although other more economical structures are typically used today. History Possibly the oldest existing arch bridge is the Mycenaean Arkadiko Bridge in Greece from about 1300 BC. The stone corbel arch bridge is still used by the local populace. The well-preserved Hellenistic Eleutherna Bridge has a triangular corbel arch. The 4th century BC Rhodes Footbridge rests on an early voussoir arch. Although true arches were already known by the Etruscans and ancient Greeks, the Romans were – as with the vault and the dome – the first to fully realize the potential of arches for bridge construction.

Aosta Cathedral
Aosta Cathedral ( it, Cattedrale di Aosta; Cattedrale di Santa Maria Assunta e San Giovanni Battista; french: Cathédrale d'Aoste; Cathédrale Notre-Dame-de-l'Assomption et Saint-Jean-le-Baptiste) is a Roman Catholic cathedral in Aosta, in north-west Italy, built in the 4th century. It is the episcopal seat of the Diocese of Aosta. In the 11th century the Palaeo-Christian structure was replaced by a new one, dedicated to the Assumption of the Virgin Mary and Saint John the Baptist. The architecture of the cathedral was modified during the 15th and 16th century. The present façade, in Neoclassical style, was built between 1846 and 1848. The structures remaining from the Romanesque period are two clock-towers and the crypt, and also the remaining part of an Ottonian fresco cycle on the church ceiling.

Flagstone
Flagstone (flag) is a generic flat stone, sometimes cut in regular rectangular or square shape and usually used for paving slabs or walkways, patios, flooring, fences and roofing. It may be used for memorials, headstones, facades and other construction. The name derives from Middle English ''flagge'' meaning turf, perhaps from Old Norse ''flaga'' meaning slab or chip. Flagstone is a sedimentary rock that is split into layers along bedding planes. Flagstone is usually a form of a sandstone composed of feldspar and quartz and is arenaceous in grain size (0.16 mm – 2 mm in diameter). The material that binds flagstone is usually composed of silica, calcite, or iron oxide. The rock color usually comes from these cementing materials. Typical flagstone colors are red, blue, and buff, though exotic colors exist. Flagstone is quarried in places with bedded sedimentary rocks with fissile bedding planes.
