Conwy Suspension Bridge
The Conwy Suspension Bridge is a Grade I-listed structure and is one of the first road suspension bridges in the world. Located in the medieval town of Conwy in Conwy county borough, North Wales, it is now only passable on foot. The bridge is now in the care of the National Trust. It originally carried the A55(T) road from Chester to Bangor. History Built by Thomas Telford, the suspension bridge spans the River Conwy next to Conwy Castle, a World Heritage Site. The bridge was built in 1822–1826 at a cost of £51,000 () and replaced the ferry at the same point. It is in the same style as one of Telford's other bridges, the Menai Suspension Bridge crossing the Menai Strait. The original wooden deck was replaced by an iron roadway in the late nineteenth century and it was strengthened by adding wire cables above the original iron chains in 1903. The following year a walkway was added for pedestrian traffic. The bridge was superseded by a new road bridge built alongside and ...

Pedestrians
A pedestrian is a person traveling on foot, whether walking or running. In modern times, the term usually refers to someone walking on a road or Road surface, pavement, but this was not the case historically. The meaning of pedestrian is displayed with the morphemes ''ped-'' ('foot') and ''-ian'' ('characteristic of'). This word is derived from the Latin term ''pedester'' ('going on foot') and was first used (in English language) during the 18th century. It was originally used, and can still be used today, as an adjective meaning plain or dull. However, in this article it takes on its noun form and refers to someone who walks. The word pedestrian may have been used in middle French in the :fr:Recueil des Croniques et Anchiennes Istories de la Grant Bretaigne, à présent nommé Engleterre, Recueil des Croniques et Anchiennes Istories de la Grant Bretaigne, à présent nommé Engleterre. In California the definition of a pedestrian has been broadened to include anyone on any ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Menai Suspension Bridge
The Menai Suspension Bridge ( cy, Pont y Borth, Pont Grog y Borth) is a suspension bridge spanning the Menai Strait between the island of Anglesey and the mainland of Wales. Designed by Thomas Telford and completed in 1826, it was the world's first major suspension bridge. The bridge still carries road traffic and is a Grade I listed structure. Background The Menai Strait was created by glacial erosion along a line of weakness associated with the Menai Strait Fault System. During a series of Pleistocene glaciations (that lasted from about 2,580,000 to 11,700 years ago), a succession of ice-sheets moved from northeast to southwest across Anglesey and neighbouring Gwynedd, scouring the underlying rock and creating a series of linear bedrock hollows. The deepest of these channels eventually became flooded by the sea as the ice sheets receded, forming the Menai Strait. As Anglesey has been an island throughout recorded human history, the only way to reach it was by crossing the st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bridges By Thomas Telford
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. Etymology The ''Oxford English Dictionary'' traces the origin of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Buildings And Structures In Conwy
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artistic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Conwy Railway Bridge
The Conwy Railway Bridge carries the North Wales coast railway line across the River Conwy between Llandudno Junction and the town of Conwy. The wrought iron tubular bridge, which is now Grade I listed, was built in the 19th century. It is the last surviving example of this type of design by Stephenson after the original Britannia Bridge across the Menai Strait was partially destroyed in a fire in 1970 and rebuilt as a two-tier truss arch bridge design. The Conwy Railway Bridge was designed by railway engineer Robert Stephenson in collaboration with William Fairbairn and Eaton Hodgkinson. The original plan had been for suspension bridge complementing Thomas Telford's Conwy Suspension Bridge of 1826. After Stephenson's appointment as chief engineer, the design was changed because a suspension bridge was considered unsuitable for trains. Stephenson and his collaborators invented the wrought-iron box-girder structure to bridge the River Conwy in a single span. During May 1846, ...

Plinth
A pedestal (from French ''piédestal'', Italian ''piedistallo'' 'foot of a stall') or plinth is a support at the bottom of a statue, vase, column, or certain altars. Smaller pedestals, especially if round in shape, may be called socles. In civil engineering, it is also called ''basement''. The minimum height of the plinth is usually kept as 45 cm (for buildings). It transmits loads from superstructure to the substructure and acts as the retaining wall for the filling inside the plinth or raised floor. In sculpting, the terms base, plinth, and pedestal are defined according to their subtle differences. A base is defined as a large mass that supports the sculpture from below. A plinth is defined as a flat and planar support which separates the sculpture from the environment. A pedestal, on the other hand, is defined as a shaft-like form that raises the sculpture and separates it from the base. An elevated pedestal or plinth that bears a statue, and which is raised from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Machicolation
A machicolation (french: mâchicoulis) is a floor opening between the supporting corbels of a battlement, through which stones or other material, such as boiling water, hot sand, quicklime or boiling cooking oil, could be dropped on attackers at the base of a defensive wall. A smaller version found on smaller structures is called a box-machicolation. Terminology The structures are thought to have originated as Crusader imitations of mashrabiya. The word derives from the Old French word ''machecol'', mentioned in Medieval Latin as ''machecollum'', probably from Old French ''machier'' 'crush', 'wound' and ''col'' 'neck'. ''Machicolate'' is only recorded in the 18th century in English, but a verb ''machicollāre'' is attested in Anglo-Latin. Both the Spanish and Portuguese words denoting this structure (''matacán'' and ''mata-cães'', respectively), are similarly composed from "matar canes" meaning roughly "killing dogs", the latter word being a slur referring to infidels.Vil ...
