What is Royal Observatory Greenwich?

The Royal Observatory Greenwich is a world-famous observatory for a multitude of reasons: not only does it contain London's only planetarium and the UK's largest refracting telescope, it is also home to the elusive Harrison timekeepers, and it is the home of Greenwich Mean Time and the Prime Meridian of the World. It is therefore the official starting point for each new day and year. Start your day with a visit to the Planetarium, which takes you all over the universe. With a combination of images from spacecraft and telescopes, and full HD projection technology, it will literally blow you away while showing you just how big the universe really is. Visit the 1675 Flamsteed House, the original observatory building at Greenwich. Walk through the beautiful Meridian Courtyard and stand right on the Prime Meridian of the World - the 0˚ longitude line. At the Time Galleries you can find out much more about the importance of timekeeping, to science, society, and organisations such as the Navy. You can touch a 4.5 billion year-old meteorite at the Astronomy Centre. After you've looked at an authentic nineteenth-century orrery, the mysteries of the universe unravel before you during a four-minute high-definition projection of how the universe was formed.
