List Of Cities In The Netherlands By Province
There are no formal rules in the Netherlands to distinguish cities from other settlements. Smaller settlements are usually called ''dorp'', comparable with villages in English speaking countries. The Dutch word for city is ''stad'' (plural: ''steden''). The intermediate category of town does not exist in the Netherlands. Historically, there existed systems of city rights, granted by the territorial lords, which defined the status of a place: a ''stad'' or ''dorp''. Cities were self-governing and had several privileges. In 1851 the granting of city rights and all privileges and special status of cities were abolished. Since then, the only local administrative unit is the municipality. Regardless of this legal change, many people still use the old city rights as a criterion: certain small settlements proudly call themselves a ''stad'' because they historically had city rights, while other, newer towns may not get this recognition. Geographers and policy makers can distinguish betw ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Conurbation
A conurbation is a region comprising a number of metropolises, cities, large towns, and other urban areas which through population growth and physical expansion, have merged to form one continuous urban or industrially developed area. In most cases, a conurbation is a polycentric urbanised area in which transportation has developed to link areas. They create a single urban labour market or travel to work area. Patrick Geddes coined the term in his book ''Cities In Evolution'' (1915). He drew attention to the ability of the new technology at the time of electric power and motorised transport to allow cities to spread and agglomerate together, and gave as examples " Midlandton" in England, the Ruhr in Germany, Randstad in the Netherlands, and the Northeastern Seaboard in the United States. The term as described is used in Britain whereas in the United States, each polycentric "metropolitan area" may have its own common designation such as San Francisco Bay Area or the Dallas ...

Roman Empire
The Roman Empire ( la, Imperium Romanum ; grc-gre, Βασιλεία τῶν Ῥωμαίων, Basileía tôn Rhōmaíōn) was the post- Republican period of ancient Rome. As a polity, it included large territorial holdings around the Mediterranean Sea in Europe, North Africa, and Western Asia, and was ruled by emperors. From the accession of Caesar Augustus as the first Roman emperor to the military anarchy of the 3rd century, it was a Principate with Italia as the metropole of its provinces and the city of Rome as its sole capital. The Empire was later ruled by multiple emperors who shared control over the Western Roman Empire and the Eastern Roman Empire. The city of Rome remained the nominal capital of both parts until AD 476 when the imperial insignia were sent to Constantinople following the capture of the Western capital of Ravenna by the Germanic barbarians. The adoption of Christianity as the state church of the Roman Empire in AD 380 and the fall of the Western ...

Bronze Age
The Bronze Age is a historic period, lasting approximately from 3300 BC to 1200 BC, characterized by the use of bronze, the presence of writing in some areas, and other early features of urban civilization. The Bronze Age is the second principal period of the three-age system proposed in 1836 by Christian Jürgensen Thomsen for classifying and studying ancient societies and history. An ancient civilization is deemed to be part of the Bronze Age because it either produced bronze by smelting its own copper and alloying it with tin, arsenic, or other metals, or traded other items for bronze from production areas elsewhere. Bronze is harder and more durable than the other metals available at the time, allowing Bronze Age civilizations to gain a technological advantage. While terrestrial iron is naturally abundant, the higher temperature required for smelting, , in addition to the greater difficulty of working with the metal, placed it out of reach of common use until the end of ...

Stone Age
The Stone Age was a broad prehistoric period during which stone was widely used to make tools with an edge, a point, or a percussion surface. The period lasted for roughly 3.4 million years, and ended between 4,000 BC and 2,000 BC, with the advent of metalworking. Though some simple metalworking of malleable metals, particularly the use of gold and copper for purposes of ornamentation, was known in the Stone Age, it is the melting and smelting of copper that marks the end of the Stone Age. In Western Asia, this occurred by about 3,000 BC, when bronze became widespread. The term Bronze Age is used to describe the period that followed the Stone Age, as well as to describe cultures that had developed techniques and technologies for working copper alloys (bronze: originally copper and arsenic, later copper and tin) into tools, supplanting stone in many uses. Stone Age artifacts that have been discovered include tools used by modern humans, by their predecessor species in the ...

Lonely Planet
Lonely Planet is a travel guide book publisher. Founded in Australia in 1973, the company has printed over 150 million books. History Early years Lonely Planet was founded by married couple Maureen and Tony Wheeler. In 1972, they embarked on an overland trip through Europe and Asia to Australia, following the route of the Oxford and Cambridge Far Eastern Expedition. The company name originates from the misheard "lovely planet" in a song written by Matthew Moore. Lonely Planet's first book, ''Across Asia on the Cheap'', had 94 pages; it was written by the couple in their home. The original 1973 print run consisted of stapled booklets with pale blue cardboard covers. Tony returned to Asia to write ''Across Asia on the Cheap: A Complete Guide to Making the Overland Trip'', published in 1975. Expansion The Lonely Planet guide book series initially expanded to cover other countries in Asia, with the India guide book in 1981, and expanded to rest of the world later on. ...

Utrecht Centraal Railway Station
Utrecht Centraal, officially Station Utrecht Centraal (), is the transit hub that integrates three bicycle parkings, two bus stations, two tram stops and the central railway station for the city of Utrecht in the province of Utrecht, Netherlands. Both the railway station and the bus station are the largest and busiest in the Netherlands. The bicycle parking station on the east side is the largest in the world. The railway station has sixteen platform tracks (of which twelve are through tracks) and 207.360 embarking and disembarking passengers per day, excluding transfers. Because of its central location in the Netherlands, Utrecht Centraal is the most important railway hub of the country with more than 1000 departures per day. History The first railway station at the site was opened on December 18, 1843, when the Nederlandsche Rhijnspoorweg-Maatschappij opened the first station on Utrecht territory. In 1938, the station became the central station as the ''Maliebaanstat ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Road Transport
Road transport or road transportation is a type of transport using roads. Transport on roads can be roughly grouped into the transportation of goods and transportation of people. In many countries licensing requirements and safety regulations ensure a separation of the two industries. Movement along roads may be by bike, automobile, bus, truck, or by animal such as horse or oxen. Standard networks of roads were adopted by Romans, Persians, Aztec, and other early empires, and may be regarded as a feature of empires. Cargo may be transported by trucking companies, while passengers may be transported via mass transit. Commonly defined features of modern roads include defined lanes and signage. Various classes of road exist, from two-lane local roads with at-grade intersections to controlled-access highways with all cross traffic grade-separated. The nature of road transportation of goods depends on, apart from the degree of development of the local infrastructure, the dista ...

Rail Transport
Rail transport (also known as train transport) is a means of transport that transfers passengers and goods on wheeled vehicles running on rails, which are incorporated in tracks. In contrast to road transport, where the vehicles run on a prepared flat surface, rail vehicles ( rolling stock) are directionally guided by the tracks on which they run. Tracks usually consist of steel rails, installed on sleepers (ties) set in ballast, on which the rolling stock, usually fitted with metal wheels, moves. Other variations are also possible, such as "slab track", in which the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a rail transport system generally encounters lower frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The operation is carried out by a railway company, providing transport between train stations or freight customer ...

Dutch Golden Age
The Dutch Golden Age ( nl, Gouden Eeuw ) was a period in the history of the Netherlands, roughly spanning the era from 1588 (the birth of the Dutch Republic) to 1672 (the Rampjaar, "Disaster Year"), in which Dutch trade, science, and art and the Dutch military were among the most acclaimed in Europe. The first section is characterized by the Eighty Years' War, which ended in 1648. The Golden Age continued in peacetime during the Dutch Republic until the end of the century, when costly conflicts, including the Franco-Dutch War and War of the Spanish Succession fuelled economic decline. The transition by the Netherlands to becoming the foremost maritime and economic power in the world has been called the "Dutch Miracle" by historian K. W. Swart. Causes of the Golden Age In 1568, the Seven Provinces that later signed the Union of Utrecht ( nl, Unie van Utrecht) started a rebellion against Philip II of Spain that led to the Eighty Years' War.
