The Royal Observatory in Greenwich is home to GMT and the Prime Meridian.

Have you ever wished you could be in two places at once? Well, you can be at the Prime Meridian of the World.

The Prime Meridian, which is located in Greenwich, England, is the longitudinal line that divides the eastern part of the world from the west (the same way the equator splits the northern and southern hemispheres).

The meridian has been an important reference point for navigators since the late 1600s and officially became known as Longitude 0º in 1884. Today, visitors flock from all over the world to stand with one foot on either side of the brass dividing line, and yes – be in two places at once.

The Greenwich Meridian is also special because it’s the home of Greenwich Mean Time – the first international time standard. It’s hard to believe that before GMT was established in the late 19th century, every town around the world just ran on whatever clock it felt like!

The Prime Meridian is located at the Royal Observatory in Greenwich, England. You can find all the transportation options here.

NB: The Observatory will be closed 7 July – 3 August 2012 due to the London Olympics.
