Definitely worth visiting if you have any interest in space, astronomy or time - and children love it. The visit combines the history of the Royal Observatory itself and the ups and downs of the Astronomer Royals who lived and worked there and the galleries...More

Had a lovely time looking around the Royal Observatory today. An interesting place. Watched a short film in the Planetarium then had a cup of tea in the cafe outside(with the squirrels). From here, learnt about watches and time-keeping. Then a stroll through the park...More

Long walk up the steep hill was well worth the visit. Lots of history to absorb. Helped by a free audio guide fascinating discoveries and inventions with some surprises (for me anyway) about the astronomers roayal.

A great way to spend a few hours and learning a thing or two about time keeping! The audio tour is definite must. Brilliant engineering to be seen in the clocks!

We spent an afternoon watching all of the shows at the planetarium, and it was good fun. Dr Ed Bloomer, the astronomer, was very funny, friendly, and knowledgeable. Beautiful park and lovely views. A very fun and easy outing!

The standardization of time. What an incredible feat and this is where it all happened. The Prime Meridian splits this site, Scientists standardized time here, mainly from a nautical standpoint so that sailors could accurately tell where they were longitudinaly. Very interesting clocks, telescopes, and...More

We visited the observatory during our recent trip to London. It took a bit of convincing of my girlfriend to go with me since she thought it would be boring, but she was incredibly surprised with how much fun it was. It is a bit...More

Located at the top of the hill in Greenwich Park, the shortest route along the path is fairly steep, so if you have mobility issues, best to stay on the road. It is longer, but the slope is more gradual. This is more than just...More

We walked to the top of the hill and also enjoyed a stroll through Greenwich park. An average experience - we had expected more.

Greenwich Mean Time starts here, so to speak, as the
very concept of global time was established at Royal
Observatory, just one of several buildings of
architectural interest in Greenwich. Indeed, the whole
of Greenwich's historic town center, its Royal Park
and a number of related buildings (and one world
famous ship, the Cutty Sark) make up the UNESCO World
Heritage site known as Maritime Greenwich. Today a

Hi! I got three questions that I hope will be answered: 1) Can tickets to the Royal Observatory be purchased on site or do I have to reserve it online? Is there a price difference? 2) Since this is obviousy a renowned tourist site, how bad are the waiting lines and what's the average waiting time to get inside? 3) I read somewhere you have to pay an extra fee to stand on the Meridian line - is this true and if so, how much is it? Thanks so much in advance!

If you go in the morning, there will probably be fewer people at the observatory. There is no charge to stand on the prime meridian line.

Does a ticket into the ROG include a planetarium show?

The standard ticket does not include a show but you can save money with an 'Astro ticket'. These can be purchased when booking a planetarium show and include entry to the historic Observatory at a discounted price... More
Hi, how long does anyone reckon you should you allow for a visit? We don't arrive in London till late morning - will there be enough time to see this in an afternoon? Obviously it depends how much you want to get into, but what would people say is usual?
