Stand astride the Prime Meridian at the Royal Observatory Greenwich
Stand with one foot in the east and one in the west and feel on top of the world at this historic observatory.
Found just off the south bank of the River Thames, the Royal Observatory in Greenwich is the only place in the world where you can stand astride the Meridian line at Longitude 0°. Marvel at the scientific discoveries that changed our understanding of time and space and see how the Astronomers Royal used to live and work.
Also known as the origin of Greenwich Mean Time, the Royal Observatory celebrates this fact with galleries dedicated to historic timekeeping devices and origin stories about why GMT was established. The site also hosts a planetarium with a wide variety of family-friendly shows, exploring the deepest reaches of space and offering exciting looks at distant planets.
Located squarely in the centre of scenic Greenwich Park, the Royal Observatory's raised seat also offers sweeping views across the city, with particularly spectacular views of Canary Wharf's skyscrapers.
Royal Observatory Greenwich is open daily from 10am to 5pm with online tickets priced at £14.40 for adults and £7.20 for children. A Day Explorer ticket can also be purchased which offers access to both the Observatory and the Cutty Sark with savings on both ticket prices.
