What a visit to the Royal Observatory Greenwich involves

A visit to the Royal Observatory Greenwich is a walk through a handful of rooms and a cobbled courtyard at the top of Greenwich Park. You go into Flamsteed House, Wren’s original observatory, for the Time and Longitude galleries and Harrison’s marine clocks, then step outside to the Prime Meridian in the yard. If you are on the hill before 1:00 p.m., and the wind allows it, the red Time Ball on the roof still drops. The onion dome holds the Great Equatorial Telescope, and from the courtyard fence the park falls away toward the Thames.

Book Royal Observatory Greenwich tickets on a timed slot. The admission card is Observatory only. The Day Pass adds Cutty Sark on the same day, a second visit once you have walked back down the hill; the ship is not a wing of these buildings. Neither card includes a planetarium show. The Peter Harrison Planetarium has been closed since 8 September 2025, and the rest of the hill stays open until 2 November 2026.

About Royal Observatory Greenwich

Royal Observatory Greenwich in Greenwich Park

Greenwich Mean Time, and the line in the courtyard

This is the observatory that gave Greenwich Mean Time its name. The metal line in the courtyard is the historic Prime Meridian, and standing across it, with Greenwich Park falling away toward the Thames, is the bit people climb the hill for. Flamsteed House, finished in 1676 for the first Astronomer Royal, still holds the rooms where that work was done: Harrison's clocks, the Octagon Room, and a view back over the park to the river.

A timed ticket is how you go in. Right now it covers Flamsteed House, the meridian courtyard, and the Great Equatorial Telescope in the onion dome. The planetarium and Astronomy Centre are closed for First Light, so the visit stays in those rooms, that courtyard, and the telescope.

What your Royal Observatory Greenwich ticket includes

Greenwich Park below the Royal Observatory Greenwich

The Prime Meridian, on the admission ticket

The metal line in the courtyard is the historic Prime Meridian of the world, defined by the Airy Transit Circle. There are three meridian marks in that yard. Airy's is the one that became longitude zero.

A Royal Observatory Greenwich ticket is how you stand on it. The cobbles are uneven.

Flamsteed House at the Royal Observatory Greenwich

Flamsteed House and Harrison's clocks, same ticket

Flamsteed House is Wren's original observatory, finished in 1676. Inside are the Time and Longitude galleries and Harrison's marine timekeepers, including H4. The Time Ball on the roof drops at 1:00 p.m. when the wind allows. That drop is included with entry.

The Octagon Room is not on the Flamsteed lift. Buggies stay outside. The admission ticket covers this building.

The Great Equatorial Telescope, still on the visit

The onion dome holds the Great Equatorial Telescope. Royal Museums Greenwich says it is over eight metres long and 71 cm wide, the largest of its kind in the UK.

It is on the paid visit. The way out is 37 spiral steps. If stairs are a problem, stay with Flamsteed House and the meridian courtyard. Both are on the same Observatory ticket.

The Octagon Room is not on the lift. There is no published locker. Stalls sit outside; Parkside Cafe is down the hill at the National Maritime Museum. Plan Your Visit has bags, photos, the Meridian Shop, and the real access map.

Know before you book Royal Observatory Greenwich tickets

Book a timed slot. Everyone on the paid visit needs a ticket.

Children under 16 go in with an adult.

The planetarium is not on these cards. Do not book them for a show on this hill.

The Day Pass is two sites in one day: the Observatory and Cutty Sark. Admission alone does not cover the ship.

The last stretch is a steep park climb unless you use the buses at the top or the Greenwich Park car park.

Questions about Royal Observatory Greenwich tickets

Do I need a ticket for the Royal Observatory Greenwich?

Yes. Everyone on the paid visit needs a ticket. The admission card covers the Observatory that is still open. The Day Pass adds Cutty Sark the same day.

What do Royal Observatory Greenwich tickets include right now?

Flamsteed House, the Prime Meridian courtyard, and the Great Equatorial Telescope. The Peter Harrison Planetarium and the Astronomy Centre are closed for First Light.

What is the difference between admission and the Day Pass?

Admission is this hill only. The Day Pass is a same-day combo: the Royal Observatory plus Cutty Sark. The ship is down the park, not inside the Observatory.

Is the planetarium included on a Royal Observatory Greenwich ticket?

No. It has been closed since 8 September 2025. The museum put a planetarium experience in the National Maritime Museum as part of Astronomers Take Over, which is a different building and a different ticket.

Can I stand on the Prime Meridian with a standard ticket?

Yes. The courtyard line is on Observatory admission. You do not need the Day Pass for that.

Is the Time Ball included?

Yes, with Observatory entry, when it runs. It drops at 1:00 p.m., GMT in winter and BST in summer. Wind can cancel it. Be on the hill before 1:00 p.m.

Does the Day Pass cover the National Maritime Museum too?

No. RMG's Day Pass is the Observatory plus Cutty Sark. The National Maritime Museum is a separate building down the hill.
