The Royal Observatory Greenwich is the historic home of British astronomy, Greenwich Mean Time and the world-famous Meridian Line. Established in the 17th century and designed by Sir Christopher Wren, it was from here that the great scientists of the time precisely mapped the stars to help navigate at sea.

Stand aside the Meridian Line with one foot in the eastern hemisphere and one in the west. Marvel at the Great Equatorial Telescope, the UK's largest historic telescope which gave astronomers new views of the universe over 100 years ago and explore the rich history of the Royal Observatory with your complimentary audio guide. While you are here don't forget to check out the live moving view in the Camera Obscura and enjoy the best view of London.

Please note that as part of an exciting redevelopment project taking place at the Royal Observatory, Flamsteed House will be closed to visitors from 1 November 2021 until 31 March 2022. The Greenwich Time Ball will also not operate during this period.

The rest of the historic Observatory, including the Prime Meridian Line, will remain open. Planetarium shows will also be running as usual.
