If we could rate this 10⭐️ we would. Science & history combined in a spectacularly articulate & mesmerising delivery - I’ve been wanting to visit this place for nearly 25 years after it got bumped off our itinerary for something else that ended up being very disappointing. So I had high expectations going in and was very excited to be there. Hubby was in tow just going with the flow and our 2 kids aged 20 and 17 had very low expectations, but tagged along, paid for by the bank of Mum & Dad and accepting that Mum will put some boring history and science things in the trip that they’ll just have to suck up.. We bought on the day a joint ticket to also see the Cutty Sark (where you have to nominate a time to be there but the lady on the desk said don’t worry, they’ll be flexible on your arrival time once you’re there, and they were). By chance our arrival was right before the morning guided tour was about to start, so we booked that. SOOOOO glad we did. Our guide was Paul. Give the man a pay rise, I’ve been on many tours in my day and have never come across a more engaging and knowledgeable guide. At the start of the day I wanted to see the Prime Meridien and get a better understanding about why longitude was so important to navigation. At the end of the tour I felt like I had enough information to pass a first year uni “historical navigation 101” exam. We learned about why the observatory was built (commissioned by Charles 2 and architect was Wren), how to read the dolphin sundial, how the astronomers used their eyes and ears to map the sky, the ground breaker that was a clock that could be used at sea to tell the time somewhere else, so you could consult your map of the sky and plot where you were. We also saw the huge telescope. We were all enthralled. Kids said at the end of the”Mum, we thought that was going to be sh*t and boring but it was so cool & awesome.” We were still chatting about it at dinner. I cannot recommend the guided tour enough. My only recommendation would be to pre advertise tour times on your website so people can plan their visits accordingly. Paul, you’re a national treasure.

Portsmouth Harbor Day - The train from London is walking distance to the harbor. It’s a great day to spent exploring the ships. HMS Victory and HMS Warrior and the Mary Rose

Greenwich Is amazing! - Please remember this is a self guided tour! Please also remember to bring headphones for your phone there are free self guided tours at museums. More knowledge than you can believe and it’s amazing! Greenwich Is a beautiful city and has a wonderful open market! Would definitely come back

What a view - The climb up the hill to the Observatory almost did me in but was worth it. Got to see the prime meridian line.

As Entertaining as it was informative - Took the trip as were into sailing and wanted to learn about lat and long. Museum is cramp packed with interesting displays and history. However we were fortunate enough to attend a chat given by MIKE D one of the volunteers. It was as entertaining as it was informative, great fun and really well delivered by Mike. I would highly recommend Mike and the team. Then at 1300 got to watch the old time signal in action. Had a great morning before we went off for a cream tea in the National Maritime Museum.

Get ticket in advance & be there at 1pm to see ball drop! - Wonderful place - go for 1pm to see the ball drop. Buy your ticket in advance to avoid queues & attend the free talks as they are really informative & explain the history of Greenwich Mean Time so well. Take the time to visit the park, National Maritime Museum & Cutty Sark. A proper day out seeing history at its best.

Highly recommend visiting this interesting place. - Get here at opening time and purchase your timed tickets in advance. Fascinating history and informative information about time.

Wonderful Greenwich trip via water taxi - We had a lovely trip me and my nephews. Very educational and lovely to see Greenwich . Everything was easily accessible. Plenty of people to help and guide. Good merchandise in the gift shops.

Great day out from London - Greenwich is a great day out from London. Lots to see, Cutty Sark, Observatory, museums, markets, lunch venues and just strolling the streets. It was an easy train ride from central London. You can easily spend 6 to 8 hours in Greenwich.

Had a great day - Observatory ; greenwich meridian; history of families of astronomers who lived there Cutty Sark National maritime museum
