Visit the home of Greenwich Mean Time (GMT), stand astride the world-famous Meridian Line and enjoy dramatic views of London across Greenwich Royal Park, the City of London and the River Thames. The Royal Observatory is the historic home of British astronomy, Greenwich Mean Time (GMT) 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 astride the Meridian Line, chosen as the Prime Meridian of the World back in 1884, with one foot in each hemisphere. Walk in the footsteps of the Royal Astronomers, discover their stories, and experience the past, present and future wonders of astronomy, space and the stars.
Must-see attractions include the Great Equatorial Telescope, Harrison’s clocks, the Shepherd Gate Clock, the Time Ball and the famous Octagon Room.
