    Are you ready to be in two places at once? Stand with one foot in the eastern hemisphere and the other in the west at London's Royal Observatory in Greenwich. In the home of space and time you will learn all about the Greenwich meridian line and GMT and how it was elected the world's supreme meridian in 1884! You will hear stories from astronomy, space and the stars and perhaps even explore the world with new dreams.

    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 Octagon room designed by Wren - also known as'The Great Star Room' - and discover John Harrison's groundbreaking inventions that have changed the world and solved the length problem.

    And don't miss the Great Equatorial Telescope, Britain's largest historical telescope, which gave astronomers new insights into the universe over 100 years ago.

    High on a hill, this landmark of London not only offers fantastic views of Greenwich, but also brings to light the wonders of time and space as you walk in the footsteps of yesterday's and today's astronomers.
