How we scored the Royal Observatory Greenwich
Our method£24 buys the Meridian Courtyard, Flamsteed House and the Great Equatorial Telescope. The famous hilltop view costs nothing.
Standing on the line where east meets west is a proper bucket-list moment, and John Harrison's sea clocks are quietly one of London's great museum exhibits.
The meridian photo queue builds from late morning. At opening you'll have the line to yourself.
The most rewarding half of a Greenwich day. Go early, then let the free park and view round it off.

Royal Observatory Greenwich FAQ
Is the Royal Observatory Greenwich worth it?▾
Worth it for the full story: standing on the Prime Meridian, Flamsteed House and John Harrison's longitude-solving sea clocks justify the £24. If you only want the view over London, that part is free from the hilltop outside the gate.
Is the view from the Royal Observatory free?▾
Yes. The panorama over Greenwich, Canary Wharf and the City is from the public hilltop in Greenwich Park, outside the paid area. The ticket covers the Meridian Courtyard, the historic observatory buildings and the galleries.
How long do you need at the Royal Observatory?▾
1.5 to 2 hours for the courtyard, Flamsteed House and the telescope. Most visitors combine it with the Cutty Sark and Greenwich Market for a full day out.
Is the planetarium included in the Royal Observatory ticket?▾
No, Peter Harrison Planetarium shows are ticketed separately. If you want a show, book a time before you plan the rest of your Greenwich day around it.
