A fingerpost on the Southdowns Way above the village of Rodmell in East Sussex marking the Greenwich Meridian. It is the line through which longitude is was measured from the Equator but no equivalent existed for longitude. Using The Royal Observatory at Greenwich the Greenwich Meridian was established and eventually became the standard line of longitude to measure time accurately - GMT or Greenwich Mean Time. Before then a mixture of methods were used to estimate time, different countries had different mehods. At the signpost in this image you will be in the western hemisphere if you face the sign and move to the left and in the eastern hemisphere if you move to the right!
