Such a stylish and elegant set of buildings, did you know they are often used by film companies as the location for their historic productions? It is easy to see why as the buildings and grounds, though old and historically important, are in excellent order

I was really excited about visiting the Observatory and Planetarium while in London for a day. The access is steep but well worth the climb for the views. There is a lot of interesting information about the progress of 'time' in many senses of the word and it was great to stand astride the meridian line. However, unless you are... More

Spend the whole afternoon there, didn't see the passing of time! Super interesting, well presented, got me completely hooked! Note: you may get joint tickets for the Cutty Sark and the Royal Observatory, definitively worth it!

Planetarium visit was brilliant, felt like i was in a different world! The staff was informative and friendly. There was a bit of a confusion with the tickets, not sure if it was because it was a quiet Sunday, but we nearly missed out planetarium show whilst queuing up for our real tickets, since we booked prior online.

I took my grandson to the Royal Observatory. We went to the Planetarium which was a show rather than a look at the stars which I found a bit disappointing.We also stood astride the Prime Meridian which is cool and visited Flamstead House where I was able to view the wonderful Harrison timepieces H1 to H4. What a genius that... More

To do this properly you need to set aside half a day as a minimum there is lots to do and see and the planetarium is partnofbthis experience but there is an extra charge for this ( a uk rip off thing) I think it should be included. The views over London are great and Greenwich park is lovely in... More

We visited in April 2013 for the Ansell Adams exhibition at the National Maritime Museum, which was wonderful. We also visited the Museum, Royal Observatory and Cutty Sark as part of our Big Ticket entrance fee. This was very good value for money. The Royal Observatory was very informative but some may find it a little too "high brow".

A great place to visit to learn about the history of clocks and sky observation. The prime meridian runs through here, which is a fun photo op! A great visit for all, and it can be done rather quickly (1 - 2 hours).

I enjoyed this very much, especially the planetarium experience, which would have been improved by being a bit longer. The steep climb up the side of the hill nearly finished me off though! It was much easier going downhill...
