Greenwich Observatory, formerly known as the Royal Greenwich Observatory (theRoyal Greenwich Observatory orRGO). The Observatory was built in Greenwich town close to the River Thames side of a hill.

From every angle, Observatory Star observation room (OctagonRoom) on top of the Red time ball (Time Ball) is striking. Observatory in 1675 by King Charles II, and Royal astronomer (AstronomerRoyal). The first astronomer John Fleming Rams Hadid (JohnFlamsteed). His tireless running in the Astral and navigation made outstanding achievements. Today, visitors can still feel he leans on hundreds of years ago. The original intention of the Observatory set up is to establish accurate navigation and location of the Datum. United Kingdom by maritime prosperity of countries, with satellite-navigation history of research and application, and the application of leading-edge ahead of the Foundation, is leading the research guide type. This is Greenwich spherical Astronomy Observatory. Along the direction of navigation within the Observatory, visible a huge black drum-type structure. This is a legacy of astronomical telescope, in this occasion. United Kingdom's Greenwich mean time (GreenwichMean TimeGMT) world famous. More famous than GMT is probably through the Greenwich Observatory of warp. When you are not in the United Kingdom, you can not use GMT, but wherever you which corner of the world, to determine your location, instead of the Prime Meridian (PrimeMeridian) as a basis, it is not possible. As the Prime Meridian to the Earth is divided into Eastern and Western hemispheres, therefore, at the Greenwich Observatory, you can stand in one location across hemispheres. This House shows clock, door in line is the Prime Meridian. Meridian wear, mastery of a symbol of the hemispheres of the globe. And is located on the ground on either side of the Meridian, carved hemispheres and important cities. Here, I do not find London nor find Ottawa and New York, I carefully looking for--the Beijing.

As far back as the Thames and the sea of sailors, whenever you see the time ball rises, you know, GMT13: 00. Now the Greenwich Observatory, in Greenwich Park (GreenwichPark). Garden grass spring onion, trees ranks due by the Observatory in Greenwich Park on the Hill. Hill top visibility not only easy to scientific observation, also let the sightseers. Park trails the aspect, the trees with Yuli. In the Greenwich Observatory of real space-time, along this Meridian to use their own pace, recalling the Observatory's history, spanning between the hemispheres.
