We took a boat from the Westminster Pier in London to the Royal Observatory in Greenwich, which was an important center for astronomy and navigation in the 17th and 18th centuries. The observatory is at the top of a high hill, which gives you a fantastic view of London, but I didn't much enjoy the walk up the hill., even... More

If you are into technical history, this is the place. It is a nice walk from the station and a fascinating look at historical artifacts associated with tracking the stars and telling time. The Cutty Sark is also near by so you can easily visit both sites in a single afternoon.

We took the river bus from London Eye which took about 40 minutes and then walked up to the observatory. It is a bit of a climb but well worth the effort. Our children enjoyed having their photo taken bestriding the prime meridian (I did too) but the highlight is the Harrison clocks. Take time to read 'longitude' before your... More

A really interesting place to visit and definitely worth looking at on a visit to London. Get a joint ticket with the Cutty Sark and both can be done in about 3 hours. Greenwich is a really nice area to walk around as well. Brilliant views of the City as well!

Its a little bit of climb if you walk through the park from the Museum but the views are great of London city and Canary Wharf. Entry to the observatory is not free but you get a headset to listen to a commentary as you walk around. It was great to see the three meridian lines and the observing equipment... More

A great place to visit. Very much outdoors, so good weather is essential. We got a joint pass to see the Cutty Sark ship and Observatory...cheaper, but still pricey. We are not touristy, but did stand in line so we could get our picture straddling the Prime Meridian separating the globe between east and west. The house for the "Astronomer... More

recently visited this attraction, it was very interesting and informative, with a multi language audio guide. The views are stunning, the parkland surrounding it is lovely to sit and relax, with plenty of eating places. There is a steep incline to reach the Observatory, but also a more gentle walk for those with mobility issues. The attraction is certainly worth... More

Staying in Greenwich

Neighborhood Profile
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.
