Royal Observatory, Greenwich


The Royal Observatory is the home of ‘Greenwich Mean Time’ and the Prime Meridian line, which divides the eastern and western hemispheres of the earth, just as the Equator divides the northern and southern hemispheres. The observatory is one of the most important historic scientific sites in the world, and has several exhibits on show to visitors. You can stand on the world-famous meridian line, visit the planetarium – and even touch a 4.5 billion year-old asteroid.
