THE GREENWICH MERIDIAN

The Greenwich Meridian separates east from west in the same way that the Equator separates north from south. Inextricably linked with Greenwich Mean Time, it also sits at the centre of our system of time zones. Its path is determined by the location of an historic telescope, the Airy Transit Circle, which is housed at the Royal Observatory, Greenwich... Such is the Meridian's fame that each year, hundreds of thousands of visitors from all around the world make their way to the Observatory to stand astride the Line.
