The meridian line in Greenwich represents the Prime Meridian of the world, Longitude Zero (0° 0′ 0″). Every place on the Earth is measured in terms of its angle east or west from this line. Since 1884, the Prime Meridian has served as the reference point for Greenwich Mean Time (GMT).
The line in Greenwich represents the historic Prime Meridian of the World – Longitude 0º. Every place on Earth was measured in terms of its distance east or west from this line. The line itself divided the eastern and western hemispheres of the Earth – just as the Equator divides the northern and southern hemispheres.
