We found the Prime Meridian!

A little disappointed in how much it cost to see George Airy's Prime Meridian, but it was a once in a lifetime opportunity. The grounds of Greenwich were pretty nice. We had a... read more

This is a great place to visit! The park itself it's lovely to walk through, and the view from the top of the hill is amazing - see how many sights you can spot! We visited the planetarium which is worth a visit, although the talks only last half an hour. The guided audio tour, which is included in the... More

This is the time of year to visit if your going by car. You can drive into the park and park right outside. The views over London are superb although they can be a bit hazy. If your interested in astronomy this is the place for you packed with displays and information. Add the Planetarium visit to your ticket and... More

A little disappointed in how much it cost to see George Airy's Prime Meridian, but it was a once in a lifetime opportunity. The grounds of Greenwich were pretty nice. We had a pleasant stroll on the surrounding grounds for free and recognized where Thor and Friends defeated the Dark Elves.

You can walk up the steep hill (long gradual pathway available for wheelchairs etc) and take in the atmosphere, see the lower outside meridian line, admire the great view over London & Canary Wharf etc without paying for entry, but if you want the full experience and visit the museums/ exhibits and see the planetarium shows, you will definitely get...

The review is about the Observatory, not the surrounding park or the village, so definitively I think it is a bit priced to get inside, mainly, as most tourists do, to get a picture in the meridian line, when you can also get the picture (maybe not as cool) from the outside. There are some exhibitions about the time when... More

I don't think so! The walk up the hill is pleasant, the views back to London are spectacular, but can't imagine what's in that observatory that's worth 10 pounds. Made me angry that prime meridian is marked on the pavement ONLY within the paid area.

To stand on the median line was fun but the audio tour of this place was all over the place. The first two exhibits was closed off but we werent told about it. Every other part of the guide told us to look to the left to see something that wasnt actually there. Evertone in the place looked as lost... More

First off I have to admit that my wife and I went to the observatory expecting to see more about the stars and so initially we were a bit disappointed. If you're interested in navigation and timepieces then it's a must but the large telescope is almost an afterthought to the attraction so having taken a whistle-stop tour we decided... More

Interesting for history buffs as this place has had a critical role in modern chronology. The highlight is the 0* line where you can stand with one foot in the East and the other in the West. Overall an interesting place to visit in a day trip when in London.

Staying in Greenwich

Neighborhood Profile
Greenwich
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.
