A must have for anyone who cares about astronomy. You get to see the original equipment, the set up, get to straddle the Great Meridian and watch the ball drop.

The Royal Observatory Greenwich is a place from where you can capture the stunning view of the city. At night it looks outstanding! Recommended to visit after 5 PM to get the effect of lights. Enough place around the observatory to relax.

Loved the royal observatory and prime meridian, was a nice spot in the rain - I would count on about 90 minutes but probably not more. Get there at 1 PM to see the big red ball drop to indicate GMT! Surrounded by a lovely...More

A good place for anyone interested in science, math, astronomy and even telecommunications history. Free audio guides are available. Recommend you bring your own headphones with jack as the museum doesn't provide them. Also check out the Planetarium in the opposite building (different set of...More

Great visit to the museum. Fun times to be had stepping over the prime meridian. Good walking shoes a must as the hill from the town of Greenwich is quite steep (albeit invigorating first thing in the morning). The exhibition inside is varied and easy...More

Learning about the challenge of designing clocks and measuring time and location was interesting. We learned a lot about why the date line is where it is. But it is more geared to adults and people that are interested in science and technology. Don't miss...More

Came here to do the planetarium but found the receptionist/ticket seller not that interested in explaining what was where and what cost what. Think with some detail would have skipped the observatory, 4 and 5 year old kids found none of it interesting. View from...More

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
