Main reason to visit Greenwich was to tour the Royal Observatory and to straddle the Prime Meridian Line. It was an unbelievable sunny day and the hike up to the observatory was exhilarating. Magnificent view of the National Museum and beyond. The observatory charged a standard admission fee. It was quite an informative visit throughout the building. The observatory museum... More

A boat trip along the Thames brought us to Greenwich especially as we wanted to visit the observatory the home of GMT. A good 15 minute walk up the hill to the entrance gives some great views across the Isle of Dogs area of London. The museum details the history of time telling how it's used in navigation especially across... More

The walk up to the observatory is worth the trip alone, the park is lovely and views on the way up and at the top are some of the best in London. We watched two of the shows at the planetarium, they were amazing! The shows are suitable for all ages, and are very informative and interesting. The museums themselves... More

Went to London on a sunny but cold February half term and chose to go to the Royal Observatory partly for the views we'd heard about. It didn't disappoint. Spectacular views of London. The attraction is reasonably priced and my teenage boys enjoyed it. Fascinating to learn how sailors learnt to navigate. Some of the descriptions were quite technical but... More

The Greenwich Royal Observatory is a good place to visit and experience history. Quite an educational tour. There is the audio guided tour which is also quite good. The view from up there is awesome specially on a bright sunny day. I found the Dolphin clock truly wonderful even though we could not see it in action. Must do place.

You can get to Greenwich by DLR or ferry boat as well as car or bus. The observatory is at the top of the hill but not far from the high street. The views are spectacular. The audio guides come with the ticket and are very informative and are available in many languages. It took us over an hour to... More

Visited here on a pre-booked ticket and was not disappointed, the presenter was good, she pitched it well to appeal to children and adults. The museum in the other building came with an audio guided tour which was very informative however could have had better instructions on where to go throughout the museum. View from the hill was very pretty.

Thank Margaret2

Staying in Greenwich

Neighbourhood 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.
