Royal Observatory 
Description
The centre of time and Longitude. The history of the Royal Observatory goes back to the Georgian era of discovery and through developments made on site here through timing devices and observations it was eventually possible to create an accurate and easy to use way of working out longitude - assisting sailors to locate where they were east or west on the planet. From this work it also led to the standardisation of time - originally as Greenwich Mean Time and these days as UTC. Through the courtyard of the observatory the Prime Meridian or 0 degrees longitude runs marking the divide between the Western and Eastern hemispheres of the globe - you can stand on either side of the line and take a photo of your feet in both East and West at once.
