Every year, thousands of people come to the Royal Observatory Greenwich to have their photograph taken on the Prime Meridian Line - Longitude 0 Degrees - as they stand in the Eastern and Western Hemispheres at the same time. But what is the purpose and history of the Greenwich Meridian?
The Royal Observatory at Greenwich is home of time and space, the Prime Meridian and Greenwich Mean Time (GMT). But have you ever stopped to ask what is the Prime Meridian and why it is Greenwich? Why are all time zones across the world based on GMT? What is longitude and why is the meridian moving?

This insightful, concise guide reveals why international time standards are based around the Greenwich meridian Longitude 0º where east meets west, and the important discoveries made at Greenwich that led to time as we know it.
