Royal Observatory closes on 2 November
The First Light project brings a whole-site closure next month. October visitors should also check the smaller gallery closures before booking.

A different Greenwich day from November
Royal Museums Greenwich lists a whole-site closure from 2 November for the First Light project.
The Time and Society Gallery also closes on 22 and 23 October. The Peter Harrison Planetarium and Astronomy Centre are already in a longer closure phase, so an Observatory ticket should not be treated as a planetarium booking.
The longer Planetarium and Astronomy Centre restriction dates from 8 September 2025. Read the closure table by named space: the two October gallery days, the existing planetarium closure and November’s whole-site closure are not interchangeable notices.

The closure dates do not describe one single reopening
Match each date to the named part of the site. The first returning courtyard is not a promise that every gallery or the planetarium will reopen with it.
| Date or phase | Published position | Planning consequence | Sources and last checked |
|---|---|---|---|
| From 8 September 2025 | The Peter Harrison Planetarium and Astronomy Centre are in a long-term closure phase. | Remove an old Observatory planetarium show from an October itinerary. A ticket for the remaining historic site does not restore that programme. | Checked . |
| 22–23 October 2026 | The Time and Society Gallery is listed as closed for both days. | If clocks and timekeeping are the essential reason for the trip, check the exact displays available before selecting these dates. This is not yet the whole-site closure. | Checked . |
| From 2 November 2026 | The Royal Observatory’s whole-site closure is listed for First Light works. | Do not use ordinary opening hours or an old combined-ticket description as evidence that the Observatory can be visited after this date. | Checked . |
| Summer 2027 plan | The Meridian Courtyard is planned to reopen in summer 2027; the project page says tickets will go on sale in January. | Wait for the actual ticket release and read what that phase includes. Neither an exact summer day nor access to the full site is confirmed here. | Checked . |
| Spring 2028 expectation | The wider First Light project is expected to be complete in spring 2028. | Keep the project update separate from a bookable visit. Recheck the current phase when planning a future trip rather than carrying forward today’s timetable. | Checked . |
| Astronomy during the works | Astronomers Take Over is at the National Maritime Museum. Its interactive experience and an experience-plus-planetarium option have different tickets. | Save the full building and product name. This offers an astronomy day, not access to the closed Observatory or the same historic interior. | Checked . |

The reopening is phased
The project page says the Meridian Courtyard is planned to reopen in summer 2027, with tickets going on sale in January.
Completion of the wider project is expected in spring 2028. Those are separate milestones: a courtyard visit and a fully reopened Observatory are not interchangeable promises.
Do not turn “summer” or “spring” into an exact arrival date. Equally, a statement that tickets will go on sale in January is not confirmation that they can already be bought or that every part of the site will be included in the first release.
Keep a future trip provisional until the relevant product and date are actually published.
If the Meridian is your main reason to go
Put the Observatory first in your planning sequence.
Choose a date shown in its booking calendar, then arrange the other parts of the day around that visit. A park walk alone cannot replace access to the historic site.
For a group with several interests, agree which experience is essential before buying a combined ticket. For an October visit, check the earlier gallery restriction against what your party wants to see, not just whether the site has a ticket left.
For a November or later trip, choose between postponing the historic-site visit and changing the purpose of the day. That is a more useful decision than trying to replace a closed interior with a photograph of the outside.
Build a useful alternative
The museum directs visitors towards astronomy experiences and space photography at the National Maritime Museum during the works.
Our advice is to select one indoor anchor, leave time for a meal and make the park optional. Save the correct building name with each booking; a Greenwich destination pin is too broad to tell you which admission you have purchased.
Astronomers Take Over has an experience-only option and an option that also includes a planetarium show. Read the actual product before promising a dome show to a child.
An alternative can preserve an interest in astronomy without being presented as the same location, ticket or historic collection.
What an October booking still needs
The final half-term programme is listed for 24 October–1 November 2026.
Individual activities have their own admission arrangements: the Halloween trail is included with general admission, while some guided activities cost extra. Check the exact listing and booking date before describing a family outing as an all-included programme.
A last opportunity before works is still subject to the normal capacity and suitability decisions; the closure notice does not establish that tickets remain available.
Recheck the ticket you already hold
If you already have a Greenwich booking, read the named attraction, date, inclusions and the terms supplied with it.
A combined product needs the same care as a single-site ticket. Contact the seller or museum about a discrepancy rather than assuming this article establishes a refund, automatic transfer or replacement show.
Save the response with the booking so every adult in the group knows what has actually been agreed.
Separate the building change from the whole district
The notice concerns the Royal Observatory, not a blanket closure of Greenwich or every Royal Museums Greenwich attraction.
Keep the original river, park and museum route only if its new indoor anchor genuinely interests the group. In poor weather, shorten the outdoor portion instead of preserving a hill climb out of habit.
Check the chosen building’s own opening and access information; an Observatory construction timetable cannot confirm another attraction’s operation.
