Experience Greenwich Prime Meridian Day Trips & Sightseeing Tours

See in England where east is separated from west the same way that the Equator separates north from south. The Greenwich Meridian, located in the Royal Observatory, Greenwich, is the universal measurement of standard time and sits at the center of our system of time zones. Its path is determined by the location of an historic telescope, the Airy Transit Circle. Hundreds of thousands of visitors from around the world visit the observatory each year to stand astride the line separating the western and eastern hemispheres.
