A prime meridian, based at the Royal Observatory, Greenwich, in London, was established by Sir George Airy in 1851. By 1884, over two-thirds of all ships and tonnage used it as the reference meridian on their charts and maps. In October of that year, at the behest of U.S. President Chester A. Arthur, 41 delegates from 25 nations met in Washington, D.C., USA, for the International Meridian Conference. This conference selected the meridian passing through Greenwich as the official prime meridian due to its popularity. However, France abstained from the vote and French maps continued to use the Paris meridian for several decades. In the 18th century, London lexicographer, Malachy Postlethwayt published his African maps showing the 'Meridian of London' intersecting the Equator a few degrees west of the later meridian and Accra, Ghana.
The prime meridian passes through the Airy transit circle (51°28′40.1″N 0°0′5.3″W / 51.477806°N 0.001472°W / 51.477806; -0.001472 (Airy Transit)) of the Greenwich observatory. It was long marked by a brass strip in the courtyard, now replaced by stainless steel, and, since 16 December 1999, has been marked by a powerful green laser shining north across the London night sky.

Greenwich (i/ˈɡrɛnɪtʃ/, /ˈɡrɪnɪdʒ/, /ˈɡrɪnɪtʃ/ or /ˈɡrɛnɪdʒ/) is an early-established district of today's London, England, centred 5.5 miles (8.9 km) east south-east of Charing Cross. The town lends its name to the Royal Borough of Greenwich.
Greenwich is generally described as being part of South-east London and sometimes as being part of East London. It is also one of the five boroughs of the London Docklands, connected to areas with docks of London historically by river and today to Canary Wharf and other buildings by the East London Line.
Greenwich is notable for its maritime history and for giving its name to the Greenwich Meridian (0° longitude) and Greenwich Mean Time. The town became the site of a royal palace, the Palace of Placentia from the 15th century, and was the birthplace of many Tudors, including Henry VIII and Elizabeth I. The palace fell into disrepair during the English Civil War and was rebuilt as the Royal Naval Hospital for Sailors by Sir Christopher Wren and his assistant Nicholas Hawksmoor. These buildings became the Royal Naval College in 1873, and they remained an establishment for military education until 1998 when they passed into the hands of the Greenwich Foundation. The historic rooms within these buildings remain open to the public; other buildings are used by University of Greenwich and Trinity Laban Conservatoire of Music and Dance.
http://tomscott.com - http://twitter.com/tomscott - If you travel to Greenwich, stand on the famous Prime Meridian Line -- which is marked with a physical line and a sculpture at the Royal Observatory -- and look at your GPS, it won't read 0° longitude. It'll be slightly out. Who's right? And why? Many thanks to my lovely cameraman Tom Morris (http://tommorris.org), who dealt with the cold wind admirably!
Time zones are based on the fact that the Earth moves 15 degrees longitude each hour. Since there are 24 hours in a day there are 24 standard time zones. (24 hours x 15º=360º) Time zones are counted from the Prime Meridian (0º longitude). Each time zone is counted at 15 º intervals and extends 7½º either side of a central meridian. For example, Sydney, Australia lies in the 150ºE central meridian, and the time zone includes all locations between 142½ºE and 157½ºE.
Both, meridians and parallels, form the geographic coordinate system based on latitude and longitude Meridians are the terrestrial geoid highs semicircles passing through the poles, imaginary lines used to determine the microseconds. By extension, are also the maximum semicircles passing through the poles of any reference sphere or spheroid. All observers located on the same meridian are at the same time, in the lighted half of Earth, the Sun at the top of its course when the Sun is at the top of the course indicating noon. By resolution, adopted at an international conference held in 1884 in Washington, and sponsored by then President of the United States, attended by delegates from 25 countries, the "reference meridian ", from which lengths are measured , i.e. , which is considered th...

Greenwich Mean Time (GMT) and the Meridian Line define the time in the world. Placed at Royal Greenwich Observatory, the Meridian Line attracts many curious visitors to Greenwich Park in London.

This video attempts to tie up some loose ends on which my other videos touch on. Many people have been telling me that our Prime Meridian is in a completely arbitrary position based solely on politics. I argue otherwise and claim there is a geological and culturally hidden reason for it's placement. This video also touches on some additional topics not yet discussed in my previous videos.
El meridiano de Greenwich es el semicírculo imaginario que une los polos y pasa por Greenwich, más precisamente por el antiguo observatorio astronómico de este suburbio de Londres. El meridiano de Greenwich sirve de meridiano de origen: es a partir de él que se miden las longitudes, en grados, es decir, que corresponde a la longitud cero, por lo que también se llama meridiano cero y primer meridiano. Se adoptó como referencia en una conferencia internacional celebrada en 1884 en Washington auspiciada por el presidente de los EE.UU., a la que asistieron delegados de 25 países.

Time to Travel visits Greenwich. The trip from Westminster Pier to Greenwich via the Thames River takes about one hour. Boatman offer a tongue and cheek narrative about history and points of interest along the River. The tour passes under Tower Bridge and passes by the modern business district at Canary Wharf. In Greenwich we tour the Old Navel College, now home to Greenwich University. We also climb to the Royal Observatory where visitors can stand astride the Prime Meridian with one foot in the Western Hemisphere and the other in the Eastern Hemisphere. This area of London will play a mayor role in the 2010 Summer Olympics. Greenwich is a great day trip but can also be done in half a day if you are pressed for time. It's well worth taking time to travel to Greenwich. This video ...
I think the Prime Meridian is pretty damn cool but London has managed to make it a really shitty experience to go and see this. Here is my video of what I thought was going to be a really cool trip to Greenwich Park in London. http://www.madmanblog.com
In many-faceted London, we'll ponder royal tombs in Westminster Abbey, discover treasures in the British Library, enjoy the vibrant evening scene in Soho, uncover Churchill's secret WWII headquarters, join the 9-to-5 crowd in the new London, shop where the queen shops, and straddle the Prime Meridian in Greenwich. © 2012 Rick Steves' Europe
Tourists flock to the Royal Observatory in Greenwich in their thousands every year to take photos of themselves standing either side of the Prime Meridian.

Cool gleaming effect created by falling snow. Filmed on 18.01.2013, Greenwich, London. Greenwich Meridian: British astronomers have long used the Royal Observatory as a basis for measurement: four separate meridians have been drawn through the building. The basis of longitude, the Prime Meridian, established in 1851 and adopted at an international conference in 1884, passes through the Airy transit circle of the observatory. It was long marked by a brass strip in the courtyard, now upgraded to stainless steel, and, since 16 December 1999, has been marked by a powerful green laser shining north across the London night sky. This old astronomical prime meridian has been replaced by a more modern prime meridian. When Greenwich was an active observatory, geographical coordinates were referr...
