Come and learn why its Greenwich Meantime that sets the world's time! Lots of models, pictures and information. A little cramped and would have loved some interaction but its the real buildings so accommodation is at a premium.

We spent most of Sunday in Greenwich. After visiting Cutty Sark and National Maritime Museum we walked up the extremely steep hill to the Observatory. This took us about 15 minutes especially as I use a walking stick to help me get around. But once...More

Nice park and walk to the small hill with observatory. Excellent view all around and real touch of the history created here. A bit pricey to get in observatory. Visited nearby planetarium, then walked down the hill to the Naval museum. Recommended.

Lovely walk (although a little steep) to the top of the hill, rewarded with a great view. Didn’t go into the Royal Observatory, but walk through the kissing gate to see the meridian line.

The story of finding longitude is fascinating and probably under rated, but it provided the foundation for mastery at sea on which the empire was built. That story is well told through the Harrison clock display at the Royal Observatory. Audio tour included in admission....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

I would say allow an hour or two at least; maybe more if you wanted to spend some time at the planetarium part; we got there rather late in the day and had to rush through , but the good part of that is it was not crowded... More
