Home of British astronomy, and the location of the world-famous Meridian Line, The Royal Observatory is one of the most iconic tourist attractions in England. Designed by Sir Christopher Wren, the building was where many of the great scientists of the 17th century would precisely map the stars in order to help navigate boats when at sea.
Since 1884 the Meridian Line has been the Prime Meridian of the World, and visitors are able to stand along the Meridian Line with one foot planted in the eastern hemisphere and one in the west. Uncover the stories of the world’s most esteemed astronomers, the Astronomers Royal, and experience the past, present and future of space. Don’t miss the Great Equatorial Telescope, the Time Ball, the Shepherd Gate Clock and Harrison’s clocks and the famous Octagon Room.
The Peter Harrison Planetarium also offers exclusive attractions, including a 4.5 billion year-old meteorite, and interactive exhibitions of how the universe was formed, how to guide a space mission and an attempt to unravel the mysteries of the cosmos.
