Visited the Royal Observatory in September and wandered around the garden area and the Maritime Museum nearby. Whilst there I saw a sign advertising their November "Night with the Stars" where you could do evening star gazing. Immediately went home and booked for this amazing experience! Unfortunately, due to unforeseen circumstances I was unable to attend the event. The ticket... More

You will have to pay to go inside the Royal Observatory area to see the major prime meridian line. But they have other places on the ground that shows the meridian and you can stand with one foot on either side. The area is lovely - tho there is a climb up a steep hill to get to the observatory.... More

The main attraction is the Prime Meridian Line, which represents the Prime Meridian of the World - Longitude 0º. Stand with a foot in each hemisphere at Longitude 0°0' 0” in the Meridian Courtyard. 20 years ago it was free but today it will cost a family of 3 about $40.00 USD to be able to straddle the prime meridian...

If you are going to visit just the Observatory be sure that you are interested in watches, telescopes and all this sort of things. I am, but my husband is not really. And actually there is nothing else to see. Except of course the idea that it is Greenwich Zero Meridian and a collection of steam pank costumes (which is... More

As an astronomer, I've been to ROG several times. I enjoy being a tourist there. Currently the Harrison clocks are down the hill at the National Maritime Museum as part of an excellent exhibition on finding longitude. So, I presume, the Steampunk idea arose in order to fill the spaces normally inhabited by the clocks and other items out on... More

Thanks for your repeated visits to our observatory and for passing on your feedback. The Longitude Punk'd exhibition was created by steampunk artists in response to the historical quest for longitude told in Ships, Clocks & Stars. Both are included in the ticket and we hope people can see both when visiting. This article by one of our curators gives... More

We thought the total package of the Royal Observatory, Cutty Sark and National Maritime Museum good value and thoroughly enjoyed our visit. We ran out of time and did not manage to do as much as would have liked but we did see was top notch and although some of the exhibits, particularly those in the Royal Observatory were not... More

It is worth the walk up the (steep) hill to get to the oibservatory. The exhibits are facinating and the staff infomative and enthusiastic. Do the planitarium show it is mind blowingly complicated!! This is the 300 anniversary of the Longitude Act so the Zero meridian really is where it all began. Dont forget to check out the viers!!

Made the effort to make the trip to the Royal Observatory only to be very disappointed. The displays were like a walk back in time to what the old fashioned museums used to be like. The route around the displays was poorly marked. The staff seemed to be grumpy and unhelpful. The displays were mostly static and non interactive. There... More

I recommend this to all visitors. Not only do you learn more about the Prime Meridian and the history associated with it; the Observatory offers you a view view on to the park and the surroundings. You can buy a big ticket that offers you entry to Cutty Sark, the observatory and one more attraction.

Its a good experience overall. But the low rating is for the price that they take. I think they need to include a guided tour to explain what all is present there given the price they are taking. Although the place is well maintained and gives you lot of photo opportunities. On another note do visit the Longitude punk d... More
