A visit to see the Meridian line was certainly on my to do list and I can certainly tick it off now. The camera obscurer and links to Christopher Wren were certainly interesting but the other exhibits were rather tired. Visitors aren't allowed to go back to use the toilets after entering the shop once the final entry time is... More

Exhibits are very interesting. Clock collection is amazing. Audio tour is helpful. Site has a lot going on. I read some postings about a place to get a free photo of the mean line at the East Park entrance at the bottom of the hill. Not worth the time unless you are not going up to the observatory. However, many... More

If you really want to stand on the Greenwich Meridian line, I would consider doing this somewhere else. It is tremendously expensive to visit this one spot, while the line technically goes around the globe, so there are numerous other places to do this. The observatory, on the other hand, is very interesting and has loads to keep you (and... More

I've always wanted to visit the Royal Observatory Greenwich and on a recent trip to London I fulfilled this wish. My wife and I stayed in Ealing and we got the tube into London where we transferred on to the Dockland Light Railway (DLR) where our final stop was Greenwich. The trip on the DLR alone was very good as... More

We walked from the Cutty Sark down by the river and up through Greenwich Park, which took us about 20 minutes. Although we were a bit puffed, the great view from the top was worth it. We could see the famous prime meridian line through the fence, but it took us a few minutes to work out that the ticket... More

The royal observatory has a £9.50 entry fee and has a tiny room with some old space observation equipment and the meridian line as displays. T is not worth the money tbh since the real gem in the scheme (the meridian line) is observable in other places in London as well for free. You won't get to do much at... More

The Prime Meridian was something I always wanted to see. I wasn't too interested in the place as a whole but walked around to get some basic information. To stand on the Prime Meridian and to think that the world gets 'measured' from here is quite a thing. We were there at 12 noon. Amazing to think that so many... More

Normally I don't like crowded places but this I had to see as I am only in Greenwich for the weekend. This is such a busy place, there is hardly any place you can browse in peace. Thankfully the free audio guide device helped a little to muffle the noise. It took a while before we got to the Prime... More

It was interesting to see the Prime Meridian and learn about Greenwich Mean Time. Found out some facts I didn't know before!

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.
