Set up by King Charles II in 1675, it's been a hub for all things astronomy, navigation, and time. You can check out telescopes, learn how sailors used the stars to find their way, and even stand with one foot in the East and one in the West!

Writing Excellent Experience with Headout We had a fantastic experience using Headout to book our tickets for the London Eye and Thames River Cruise. The booking process was quick, easy, and straightforward, and everything went smoothly on the day. The tickets were convenient to access, and both experiences were enjoyable and well organised. The London Eye offered spectacular views of London, while the Thames River Cruise was a wonderful way to see the city from a different perspective. We were very happy with the service from Headout and would definitely use them again for future attractions and experiences. Highly recommended!

After I selected my language, the audio guide kept speaking in English. That was the only downside of the visit. Otherwise, entry was quick, and there were written explanations in all languages at many points along the way, which allowed us to learn about the tower’s history.

An incredible journey through the history of the UK and maritime adventures, brought vividly to life through the stories of sailors and the beautifully preserved artifacts like the iconic Cutty Sark! We were also fortunate to be welcomed by lively shanty singers, adding to the atmosphere. Concluding our visit, we enjoyed a delicious brownie at the dry dock, making for a truly memorable experience.
