Royal Observatory, Greenwich

The Royal Observatory, Greenwich (known as the Royal Greenwich Observatory or RGO when the working institution moved from Greenwich to Herstmonceux after World War II) is an observatory situated on a hill in Greenwich Park, overlooking the River Thames. It played a major role in the history of astronomy and navigation, and is best known as the location of the prime meridian. The scientific work of the observatory was relocated elsewhere in stages in the first half of the 20th century, and the Greenwich site is now maintained as a museum.
