Came on Saturday after visiting the Cutty Sark. All the staff we encountered were friendly I just found the experience a little too old for our daughter (8) she lost interest really quickly. We will try again in a few years

The audio guide is good but poorly explained and signposted. Also only available in a small number of languages. Very crowded. Lots of steps. Staff not very knowledgeable

Nice park hill to walk up for views over the East End and City. Forget the £10 entry fee, just have a quick pose over the Meridian, one foot in the World's East, one in the West.

We all loved the observatory. Lots of history and interesting facts. We also took in a show at the planetarium. Is an astronomy fans dream and very entertaining and interesting for every one else.

Different from many other observatories which are dedicated to pure astronomical observations, the Royal Observatory Greenwich was dedicated to navigation, timing and positioning, which is why people agreed to have the prime meridian based on the place. And just like most other observatories it's on...More

It's a wonderful observatory building, filled with history and some really interesting timepieces including several designed by John Harrison on the way to his winning the prize for a chronometer accurate enough for navigation. It shows how the great minds of the day were applied...More

Yes, you can. I think the longest you can spend doing the Royal Observatory (this is listening to absolutely all of the audio guide) should be about 2 hours at most; The museum is not huge. Cutty Shark might take longer... More

There is an awful lot to do around Greenwich and plenty of places of interest. Sea life aquarium is interesting but there are lots of cities with aquariums but there is only one Royal Observatory.
