Royal Observatory Greenwich: the Meridian, hill and closure plan
The home of Greenwich Mean Time sits above one of London’s strongest museum districts. Choose the historic site, the hill route and the date carefully: the planetarium is already closed, with the whole Observatory closing from 2 November 2026.
What the visit covers
The Observatory connects astronomy, navigation, clocks and the Prime Meridian.
The Peter Harrison Planetarium and Astronomy Centre have been closed since 8 September 2025; the remaining historic site is a different booking. Give the historic visit a question rather than a list of photo stops: how did clocks help a ship work out its position, and why did a reference meridian matter?
Let the group choose between timekeeping, navigation and the Meridian before buying. A child who wants a darkened dome show may be asking for a different experience from an adult who wants Harrison’s clocks.

Source review needed. This planning check is older than seven London days or unavailable. Older event checks are excluded below; verify current details with the linked organisers.
The practical details
- Official opening information
- Normally 10:00–17:00, last entry 16:00, before the whole-site closure from 2 November 2026. Do not plan November or December admission. Check smaller gallery closures too.
- Free or paid
- The checked page advertises adult £24 and child £12; members free. A price does not override the closure.
- How to book
- Choose an available date before closure on the official calendar; same-day entry is subject to availability.
- Station and journey
- Cutty Sark DLR or Greenwich, followed by the hill approach. Check the access route rather than assuming the photographed path is suitable.
- Accessibility
- The official access directory links a separate Observatory guide. Historic rooms, the hill and courtyard surfaces need their own planning; not every area is step-free.
- When to visit
- Choose the date before paying for the rest of the day. The planetarium and Astronomy Centre are already closed; another museum’s astronomy activity is not on this site.
- Food nearby or on site
- The organiser lists refreshments near the entrance and Parkside Café downhill at the National Maritime Museum.
- Nearby free ideas
- National Maritime Museum and Queen’s House are free alternatives with their own entry rules; Cutty Sark is paid.

How to get there
Cutty Sark DLR or Greenwich, followed by the hill approach. Check the access route rather than assuming the photographed path is suitable. Use the London transport guide to plan the whole journey, and confirm service changes with the operator before travelling.
LONNOW PLANNING DESK
Choose the Greenwich experience that is actually open
A historic Observatory visit, a planetarium show and a park walk are different experiences. Start with the building and date, then buy the matching admission.
| Your main interest | Recorded position | What to arrange | Sources and last checked |
|---|---|---|---|
| The Meridian and historic Observatory | The remaining historic site is open ahead of the whole-site closure from 2 November 2026. The Time and Society Gallery has an earlier restriction on 22–23 October. | Choose an available October date in the official booking calendar and check the closure list as well as the ticket description. | Checked . |
| A planetarium show | The Peter Harrison Planetarium and Astronomy Centre have been closed since 8 September 2025. An Observatory ticket is not a booking for a show there. | For a current Greenwich show, inspect Astronomers Take Over at the National Maritime Museum; select its planetarium option rather than assuming the exhibition-only ticket includes it. | Checked . |
| The hill, cobbles and a buggy | The access page describes the hill, uneven courtyard cobbles and restrictions on buggies in Flamsteed House. A park viewpoint does not establish an accessible route through the paid site. | Check the current approach and internal route with the museum. If somebody needs a wheelchair loan or other assistance, settle that before fixing the rest of the day. | Checked . |
| An October half-term activity | The Observatory lists a 24 October–1 November 2026 programme. Its Halloween trail is included with general admission; some separately described tours cost extra. | Choose a named activity and check that item’s date, age guidance and inclusion. Do not treat the programme heading as one ticket covering every tour. | Checked . |
| A visit from November onwards | The First Light plan separates a summer 2027 Meridian Courtyard reopening from expected wider-project completion in spring 2028. | Do not buy travel on the assumption of a fully reopened Observatory in summer 2027. Use a confirmed alternative building until the relevant booking opens. | Checked . |

Choose the date before the ticket
Check the closures page before the booking calendar.
The Time and Society Gallery closes on 22 and 23 October 2026, and the whole Observatory closes from 2 November for First Light works. A generic daily-opening panel is not evidence that a closed part is available.
Arrive with margin for the walk uphill and ticket checks; for any separately booked activity, follow the admission time on that booking. The project’s summer 2027 courtyard plan and spring 2028 wider completion expectation are separate future phases, not a reason to assume normal admission after November.
For a party travelling mainly for the Meridian, settle this date constraint before paying for other parts of the Greenwich day.
Plan the Greenwich hill
The route from Cutty Sark or Greenwich station climbs through the park.
Visitors with limited mobility should check accessible transport, entrances and routes rather than assuming the most photographed path is suitable. The museum specifically flags uneven courtyard cobbles and says buggies cannot enter Flamsteed House’s narrow galleries.
A route that reaches the entrance is not necessarily suitable inside. Check the current approach, any equipment loan and the areas your group can use; do not make somebody wait outside simply because the hill looked manageable on a map.
Combine one nearby museum
The National Maritime Museum, Cutty Sark and Queen’s House are close, but each can be substantial.
Pair the Observatory with one additional anchor and leave space for the park and river. During the works, Astronomers Take Over at the National Maritime Museum offers an interactive astronomy experience and a separately selectable planetarium option.
Save that building name, not just “Greenwich”. On a wet day it can provide the indoor anchor; make the hill and park an optional walk rather than the compulsory link between two tightly timed bookings.
Check the sky calendar
Astronomy events, observing opportunities and show schedules change.
Use Royal Museums Greenwich for current programming and never rely on an old event listing for a date-specific visit. Read the location as well as the event name: Royal Museums Greenwich operates several buildings.
A programme associated with its astronomers is not automatically on the Observatory hill, and a photograph of the old dome does not establish where a new show takes place.
Half term: choose a named activity
The Observatory’s published October half-term programme runs from 24 October to 1 November 2026, immediately before the whole-site closure.
It includes a Halloween trail with general admission, while some named tours have an extra charge. Start with the individual activity description rather than a blanket assumption about what a ticket includes.
For mixed ages, agree whether the family wants a self-paced trail or a guided activity; leave space to look at the historic site instead of treating the programme as a race between sessions.
Download before climbing
The access page describes a free Smartify audio guide with 17 chapters, including Flamsteed House, the Octagon Room, Harrison’s clocks and the Meridian.
Download what you need and bring headphones rather than depending on mobile reception at a specific display. The museum also lists sensory information and ear defenders available from the ticket office.
These are useful questions to ask in advance, not a promise that the site will be quiet or that every area meets every visitor’s access needs.
