Purchasing tickets in Headout is very simple, and what I like the most you see your upcoming appointments. No need to search through mail inbox or print the tickets. The Observatory is nice, my kids enjoyed it a lot.

Stand on the Prime Meridian
Your Royal Observatory Greenwich tickets allow you to explore the home of the Greenwich Mean Time. Revel in the feeling of standing on the Prime Meridien, the line that splits the Earth into the eastern and western hemispheres. This is an excellent place to grab a photograph of yourself! Take the opportunity to learn about the story behind the Greenwich Mean Time from your multilingual audio guide. You can also choose to upgrade your tickets to the Royal Museums Greenwich Day Pass which allows you to access the Observatory, the famous Cutty Sark ship, the National Maritime Museum, and Queen's House.
The icons of Greenwich
Learn more about the ingenious clocks made by John Harrison to help sailors determine their longitude at sea, drastically reducing the danger of ships, crew, and cargo being lost to the waters. The clocks themselves look incredibly sophisticated and beautiful. There are four versions of the clocks, H1 to H4, the H1 having been released in 1735. Along with others, it was widely heralded as a great milestone in the history of clock-making. Take the chance to stand beneath the Great Equatorial Telescope, a 28-inch refracting telescope that is the largest of its kind in the UK. Originally designed for astrophotography, it has become indispensable for the observatory's research into double stars. Don't miss out on seeing the telescope's distinct "onion roof" when you look up at the Royal Observatory.
