Located in the centre of Greenwich park, the Royal Observatory sits on a hill with a commanding view over London - worth a walk up just for that, though it is quite steep. The museum itself has lots of information and history on the Royal Observatory, particularly with emphasis on the problems in measuring time and longitude with regards to... More

It's a hike to make it up to the Royal Observatory (if you're walking) - especially after it's rained, the leaves are all slippery! But it's worth the trip the view at the top (even on the way up) is stunning. The observatory itself was great. The audio tour definitely adds more information and background. It was neat to see...

We really had high hopes for the observatory. Planned our holiday for it, and although the town and views were lovely, inside the observatory the museum information was just too difficult to follow. My boyfriend and I are quite techie and we read and re-read things and couldn't make sense, and the displays were just too dry and boring so... More

What a wasted opportunity to make science interesting. Finding it is difficult unless you know how to get there, the signs are few and far between. When you get there the audio guided tour is very poor with ipads that don't always work and really terrible signage. If you leave in the dark you risk life and limb leaving because... More

Never having been to this famous landmark we decided to give it a go. It was well worth visiting the extensive grounds are well maintained its a piece of calm in the London conurbation. The views from the top of the hill are fantastic on a clear day and the Observatory was well worth a visit, you are supplied a... More

With a young boy (5) who is interested in space and time this was a great activity it fills roughly half a day (I recommend being there for the ball drop measure at 12.55 daily). The planetarium has a great basic show suitable for 3+ (though not if anyone is scared of the dark). There is a family workshop run... More

My main reason for coming here was to stand on the Prime Meridian, the place from where time is measured and East meets West, and I was not disappointed. The absence of crowds due to a very rainy day made my experience more intimate and enjoyable. I was fascinated by the magnificent views at the top of the Observatory. Be... More

Getting to Greenwich is half the fun! We walked, we took the bus, the tube, a boat on the Thames and the DLR.... All with our Oyster card (be sure to purchase for public transportation and top off as needed). Beautiful observatory and very informative. Home of Greenwich mean time. Be sure to see a planetarium show, which is live... More

Staying in Greenwich

Neighborhood Profile
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 laser beam is shot out across the night sky from the Observatory to mark the location of the Prime Meridian. Other bold (some say brash) 21st century additions to the area include landmarks such as The O2 entertainment complex (previously known as the Millennium Dome) and the Air Line cable cars, which offer scenic transport across the Thames between North Greenwich and the Royal Docks.
