From one time to another! Really that’s what you can do. One second you’re in the Eastern hemisphere and the next the Western hemisphere. Welcome to the Royal Observatory, home to the GMT and the Meridian line. Not only can you learn about time, space and the stars, you’ll also get a fantastic view across London.
Ever thought about exploring? Then this place may be the inspiration. Get your timing right, and you can see the Time Ball drop (an early public time signal). That’s at 1300 if you’re interested. Stand in Charles II’s magnificent Wren-designed Octagon Room – also known as 'The Great Star Room', and discover John Harrison's groundbreaking inventions that changed the world and solved the longitude problem. Don’t miss the Great Equatorial Telescope, the UK’s largest historic telescope which gave astronomers new views of the universe over 100 years ago.
This is one of London’s premier landmarks, so make sure to give it some time!
