You do need to be a bit of a history, clock, or astronomy fan, but it is fascinating. The original Harrison clocks that made it possible for ships to safely plot their longitude are on display and you can participate in a very thorough guided tour. You can also stand on the 0 longitude line and be half in the... More

If your a navigation, geography of a time-keeper buff, you'll be well rewarded. The Greenwich Meridian was established here. John Harrison original marine chronometer are here in all the artistic and engineering glory.

If you come, you can have a quick look around, take the obligatory photo on the meridian line, and go home - or you can spend hours learning about some of the most interesting discoveries in the history of what is perhaps the oldest science. Either way, absolutely worth the trip.

Quite pricey to get in then really not up to the standard of a lot of the free museums in the city audio tour is pretty useless

This is a place I have wanted to visit for years. Finally got round to it today. Amazing views over London on what was a very windy day. Loved the photography exhibits inside and the planetarium was amazing. The story teller was very inspiring to listen to. Makes you realise how small but special we humans are.

It was a nice and interesting place to visit. It is quiet expensive and the whole museum is small BUT I loved it. The park around the observatory is very beautiful.

Came here on a lovely summer's day and arrived by boat on the Thames. The walk up the hill to the observatory was nice and you get a nice view over the Thames and Greenwich. + The museum is pleasantly laid out and the grounds are nice You can run through the museum part quite quickly, but to make the...

Great museum to visit, fascinating facts, learnt lots of very interesting things. Such a shame visit slightly ruined by very rude staff member. My Husband and I were queuing to have picture taken with the Greenwich Meridian. Very big queue, waited about 15 minutes in queue realising we weren't actually moving anyway as other people were just walking up to... More

This was a really enjoyable visit to appreciate what it means for everyone to have agreed on a standard time and time zones. The impact would be far reaching for the technology we have today if time was not standardised and synchronised. The planetarium was also impressive but why, oh why must parents bring toddlers and very young children to... More

Staying in Greenwich

Neighbourhood 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.
