About Royal Observatory

Ever wondered where time begins? Head to the Royal Observatory Greenwich to find out! This observatory is where the world's time zones are measured from – the Prime Meridian Line, 0° longitude, runs right through it! Perched on Greenwich Hill, you'll get amazing views of London, too. Set up by King Charles II in 1675, it's been a hub for all things astronomy, navigation, and time. You can check out telescopes, learn how sailors used the stars to find their way, and even stand with one foot in the East and one in the West!

The London eye had amazing sights and not a long wait. If you have time to do this experience it's a must see on your list for London. As for the Thames cruise we ran out of time and couldn't use it so only get it if you know you will have time to use the combo pass to both attractions I tried to get a different time but policy is strict. The customer service was nice nonetheless when I asked them.

The captain gave an excellent talk on many of the sites we passed on our cruise down to Greenwich. We were told more about our first stop, the Cutty Sark. Our favourite.
