Royal Observatory Greenwich
Science & Technology Museums
The historic home of GMT and the Prime Meridian
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.
