Ready to be in two places at once? Stand with one foot in the eastern hemisphere and one in the west at London's Royal Observatory in Greenwich. 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.
Time your visit to coincide with the dropping of the bright red Time Ball on top of Flamsteed House, one of the world’s earliest public time signals. It drops daily at 13:00.
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 London landmark high on a hill not only offers awesome Greenwich views, but it brings the wonders of time and space to light as you walk in the footsteps of astronomers, past and present.
