Causeway
A causeway is a track, road or railway on the upper point of an embankment across "a low, or wet place, or piece of water". It can be constructed of earth, masonry, wood, or concrete. One of the earliest known wooden causeways is the Sweet Track in the Somerset Levels, England, which dates from the Neolithic age. Timber causeways may also be described as both boardwalks and bridges. Etymology When first used, the word ''causeway'' appeared in a form such as "causey way", making clear its derivation from the earlier form "causey". This word seems to have come from the same source by two different routes. It derives ultimately, from the Latin for heel, , and most likely comes from the trampling technique to consolidate earthworks. Originally, the construction of a causeway used earth that had been trodden upon to compact and harden it as much as possible, one layer at a time, often by slaves or flocks of sheep. Today, this work is done by machines. The same technique w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Causewayed Enclosure
A causewayed enclosure is a type of large prehistoric Earthworks (Archaeology), earthwork common to the early Neolithic in Europe. It is an enclosure (archaeology), enclosure marked out by ditches and banks, with a number of causeways crossing the ditches. More than 100 examples are recorded in France and 70 in Southern England and Wales, while further sites are known in Scandinavia, Belgium, Germany, Italy, Ireland and Slovakia. The term "causewayed enclosure" is now preferred to the older term, causewayed camp, as it has been demonstrated that the sites did not necessarily serve as occupation sites. Archaeologists have speculated on the purposes of such sites, but have not arrived at a consensus as to their function. Construction Causewayed enclosures are often located on hilltop sites, encircled by one to four concentric ditches with an internal Bank (geography), bank. Enclosures located in lowland areas are generally larger than hilltop ones. Crossing the ditches at int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hindenburgdamm
The Hindenburgdamm or Hindenburg Dam is an 11 km (7 mile) long causeway joining the North Frisian island of Sylt to mainland Schleswig-Holstein. Its coordinates are . It was opened on 1 June 1927 and is exclusively a railway corridor. The companies that built the Hindenburgdamm, a job that took four years, were Philipp Holzmann AG of Frankfurt, working from the mainland, and Peter Fix Söhne of Duisburg working from Sylt. A train trip along the causeway takes about 10 minutes, and the time between the auto terminals at Niebüll on the mainland and Westerland on Sylt is about 30 minutes. The Hindenburgdamm is part of the railway line known as the ''Marschbahn'' (" Marsh Railway"), which is double-tracked along much of the route, although there as yet exists a single-tracked stretch. On the causeway is a signal box. The rail line is not electrified making the use of diesel locomotives necessary. Trains coming from origins further south like Hamburg change from an electri ...

Somerset Levels
The Somerset Levels are a coastal plain and wetland area of Somerset, England, running south from the Mendips to the Blackdown Hills. The Somerset Levels have an area of about and are bisected by the Polden Hills; the areas to the south are drained by the River Parrett, and the areas to the north by the rivers Axe and Brue. The Mendip Hills separate the Somerset Levels from the North Somerset Levels. The Somerset Levels consist of marine clay "levels" along the coast and inland peat-based "moors"; agriculturally, about 70 per cent is used as grassland and the rest is arable. Willow and teazel are grown commercially and peat is extracted. A Palaeolithic flint tool found in West Sedgemoor is the earliest indication of human presence in the area. The Neolithic people exploited the reed swamps for their natural resources and started to construct wooden trackways, including the world's oldest known timber trackway, the Post Track, dating from about 3800 BC. The Le ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tenochtitlan
, also known as Mexico-Tenochtitlan, was a large Mexican in what is now the historic center of Mexico City. The exact date of the founding of the city is unclear, but the date 13 March 1325 was chosen in 1925 to celebrate the 600th anniversary of the city. The city was built on an island in what was then Lake Texcoco in the Valley of Mexico. The city was the capital of the expanding Aztec Empire in the 15th century until it was Fall of Tenochtitlan, captured by the Tlaxcaltec and the Spanish in 1521. At its peak, it was the largest city-state, city in the pre-Columbian Americas. It subsequently became a ''Municipalities of Mexico, cabecera'' of the Viceroyalty of New Spain. Today, the ruins of are in the historic center of the Mexican capital.

Sylt
Sylt (; ; Söl'ring North Frisian: ) is an island in northern Germany, part of Nordfriesland district, Schleswig-Holstein, with a distinctively shaped shoreline. It belongs to the North Frisian Islands and is the largest island in North Frisia. The northernmost island of Germany, it is known for its tourist resorts, notably Westerland, Kampen and Wenningstedt-Braderup, as well as for its sandy beach. It is frequently covered by the media in connection with its exposed situation in the North Sea and its ongoing loss of land during storm tides. Since 1927, Sylt has been connected to the mainland by the Hindenburgdamm causeway. In later years, it has been a resort for the German jet set and tourists in search of occasional celebrity sightings. Geography With , Sylt is the fourth-largest German island and the largest German island in the North Sea. Sylt is located from off the mainland, to which it is connected by the Hindenburgdamm. Southeast of Sylt are the islands ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Timber Trackway
Historic roads (or historic trails in the US and Canada) are paths or routes that have historical importance due to their use over a period of time. Examples exist from prehistoric times until the early 20th century. They include ancient trackways, long-lasting roads, important trade routes, and migration trails. Many historic routes, such as the Silk Road, the Amber Road, and the Royal Road of the Persian Empire, covered great distances and their impact on human settlements remain today. The Post Track, a prehistoric causeway in the valley of the River Brue in the Somerset Levels, England, is one of the oldest known constructed trackways and dates from around 3800 BCE. The world's oldest known paved road was constructed in Egypt some time between 2600 and 2200 BC. The Romans were the most significant road builders of the ancient world. At the peak of the Roman Empire there were more than of roads, of which over were stone-paved. Another empire, that of the Incas of pre-C ...

Sweet Track
The Sweet Track is an ancient trackway, or causeway, in the Somerset Levels, England, named after its finder, Ray Sweet. It was built in 3807 BC (determined using dendrochronology – tree-ring dating) and is the second-oldest timber trackway discovered in the British Isles, dating to the Neolithic British Isles, Neolithic. The Sweet Track was predominantly built along the course of an earlier structure, the Post Track. The track extended across the now largely drained marsh between what was then an island at Westhay and a ridge of high ground at Shapwick, Somerset, Shapwick, a distance close to or around . The track is one of a network that once crossed the Somerset Levels. Various artifacts and prehistoric finds, including a jadeitite ceremonial axe head, have been found in the peat bogs along its length. Construction was of crossed wooden poles, driven into the waterlogged soil to support a walkway that consisted mainly of planks of oak, laid end-to-end. The track was ...

Neolithic
The Neolithic or New Stone Age (from Ancient Greek, Greek 'new' and 'stone') is an archaeological period, the final division of the Stone Age in Mesopotamia, Asia, Europe and Africa (c. 10,000 BCE to c. 2,000 BCE). It saw the Neolithic Revolution, a wide-ranging set of developments that appear to have arisen independently in several parts of the world. This "Neolithic package" included the History of agriculture, introduction of farming, domestication of animals, and change from a hunter-gatherer lifestyle to one of sedentism, settlement. The term 'Neolithic' was coined by John Lubbock, 1st Baron Avebury, Sir John Lubbock in 1865 as a refinement of the three-age system. The Neolithic began about 12,000 years ago, when farming appeared in the Epipalaeolithic Near East and Mesopotamia, and later in other parts of the world. It lasted in the Near East until the transitional period of the Chalcolithic (Copper Age) from about 6,500 years ago (4500 BCE), marked by the development ...

Norman Language
Norman or Norman French (, , Guernésiais: , Jèrriais: ) is a ''Langues d'oïl, langue d'oïl'' spoken in the historical region, historical and Cultural area, cultural region of Normandy. The name "Norman French" is sometimes also used to describe the administrative languages of ''Anglo-Norman language, Anglo-Norman'' and ''Law French'' used in England. For the most part, the written forms of Norman and modern French are mutually intelligible. The thirteenth-century philosopher Roger Bacon was the first to distinguish it along with other dialects such as Picard language, Picard and Burgundian language (Oïl), Bourguignon. Today, although it does not enjoy any official status outside of Jersey, some reports of the French Ministry of Culture (France), Ministry of Culture have recognized it as one of the regional languages of France.

Wadden Sea
The Wadden Sea ( ; ; or ; ; ; ) is an intertidal zone in the southeastern part of the North Sea. It lies between the coast of northwestern continental Europe and the range of low-lying Frisian Islands, forming a shallow body of water with tidal flats and wetlands. It has a high biodiversity, biological diversity and is an important area for both breeding and migrating birds. In 2009, the Dutch and German parts of the Wadden Sea were inscribed on UNESCO's World Heritage List and the Danish part was added in June 2014. The Wadden Sea stretches from Den Helder, in the northwest of the Netherlands, past the great river estuaries of Germany to its northern boundary at Skallingen in Denmark along a total coastline of some and a total area of about . Within the Netherlands, it is bounded from the IJsselmeer by the Afsluitdijk. Historically, the coastal regions were often subjected to large floods, resulting in thousands of deaths, including the Saint Marcellus' floods of 1219 and 136 ...

Boardwalk
A boardwalk (alternatively board walk, boarded path, or promenade) is an elevated footpath, walkway, or causeway typically built with wooden planks, which functions as a type of low water bridge or small viaduct that enables pedestrians to better cross wet, muddy or marshy lands. Such timber trackways have existed since at least Neolithic times. In many seaside resort locations, boardwalks along the beach provide access to shops, hotels, and tourist attractions. The Jersey Shore in the United States is especially noted for its abundance of boardwalks. Some wooden boardwalks have had sections replaced by concrete and even "a type of recycled plastic that looks like wood." History An early example is the Sweet Track that Neolithic people built in the Somerset levels, England, around 6000 years ago. This track consisted mainly of planks of oak laid end-to-end, supported by crossed pegs of ash, oak, and lime, driven into the underlying peat. The Wittmoor bog tra ...
