At the home of space and time, you'll learn all about the Greenwich Meridian Line and GMT, and how it was chosen to be the Prime Meridian of the world back in 1884! You'll hear stories of astronomy, space and the stars, and you might even leave with fresh dreams of exploring the world.

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.
