What Travellers Say
The Royal Observatory Greenwich is one of those places that feels special the moment you arrive. Sitting at the top of Greenwich Park, the walk up is a bit of a climb, but the views waiting at the top make it completely worth it. You get a beautiful look over the Thames and across London, which already sets the mood before you even step inside. The most memorable part is standing on the Prime Meridian line. It’s a simple photo moment, but knowing you’re standing at the point where the world measures time and longitude gives it real meaning. Inside, the exhibits are clear and engaging, even if you’re not deeply into science. The historic clocks and timekeeping displays tell a fascinating story about how sailors once depended on this place to navigate the world. What I liked most was how calm and unhurried the experience felt. You can take your time, read, look around, and really absorb the history. The planetarium is also worth seeing if you have time. Overall, the Royal Observatory Greenwich is interesting, peaceful, and genuinely inspiring. It’s a great mix of learning, history, and atmosphere, and a place I’d happily recommend to anyone visiting London.

History & Science: The exhibits about timekeeping and navigation are fascinating and presented in a way that is engaging for both adults and children. The View: The panoramic view from the top of the hill over Greenwich Park and the London skyline (Canary Wharf) is absolutely breathtaking. Summary: A perfect mix of education and fun. If you are visiting London, this historic site is a must-see. We highly recommend it for families!
Always a great experience. My daughter is studying a course run by the observatory staff. They are so helpful, welcoming and knowledgeable. The grounds of the park are beautiful. I love taking my daughter to the observatory and maritime museum and walking round the park is a a delight. Highly recommend this as a lone visitor, as a romantic day out or as a family trip.
I enjoyed walking around the grounds and learning. If you pay for the exhibit bring your headphones. They provide a tour you can listen to on your phone. This guide also has sign language as well as many different language options. The museum is small but had a lot of educational value add. It does cost to enter, adults are £24. It would be a great tour to take a child on.
Had a great time looking around the Royal Greenwich Observatory, the history of this place is amazing so much to see. The location in Greenwich Park over looking the city is probably one of the best views of London anywhere. The Harrison clocks are a fascinating part of history, they are truly amazing.

At 3.14pm on 10 August 1675, John Flamsteed laid the observatory’s foundation stone, and he moved into Flamsteed House less than a year later on 10 July 1676.
The Shepherd Gate Clock, installed in 1852, was the first clock ever to show Greenwich Mean Time directly to the public, and its 24-hour dial means noon points straight down.

The green Meridian laser above the Airy Transit Circle was first set up in 1993, and under excellent conditions it has been seen from as far as 36 miles away.
The 28-inch Great Equatorial Telescope is round at each end but square in the middle because its mount had originally been made for a smaller telescope and the new tube had to be squeezed to fit.
