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 by King Charles II 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. The historic observatory is now a museum focusing on making the history and subject of astronomy accessible for all.
