A visit to the Cutty Sark is interesting, but going to the Royal Observatory is fascinating—especially the view from the top. And it’s definitely worth taking the boat ride along the Thames to get there.

The Greenwich Observatory is a must-see that you can't find anywhere else in the world! 4 out of 5 stars—only because the section dedicated to astronomy is unfortunately closed until 2027.

Beautiful place. Quite interesting. Maybe not enough explanations for kids ( especially at the Observatory).
