Stand astride the world-famous Meridian Line, with one foot in the east and the other in the west, at the home of GMT (Greenwich Mean Time)

Discover the past, present and future wonders of astronomy at the centre of time! Take a fascinating journey through the historic home of British astronomy, Greenwich Mean Time and the Prime Meridian of the World and explore Flamsteed House, the original astronomer’s apartments. 

Up on the summit of Greenwich Park, the Royal Observatory takes central stage and promises visitors an educational historical visit. It’s one of the world’s most important scientific sites and you can learn about how time was standardised, how the first telescope was made and how science has changed through the ages.

Learn about how great scientists first mapped the seas and the stars and stand astride two hemispheres on the Prime Meridian Line; see pioneering inventions and the UK’s largest refracting telescope; touch a 4.5 billion year-old asteroid and enjoy breath-taking views across the whole of London. 

All with no further entry with The London Pass!

Special closures: On most Mondays during term-time, the Great Equatorial Dome will be closed at times between 10.00–14.30 for educational sessions.

Please note: The site is wheelchair accessible but please note that the route to the site is up a very steep hill.
