The planetarium in Greenwich Park is the only place in the capital where you go for a tour of the universe. These days, with CGI technology, the Planetarium has raised its game, with state-of-the-art graphics and stunning films revealing the latest scientific discoveries. Shows include Space Safari, which is suitable for children under eight.

While in Greenwich, why not hop across the river and explore London’s vibrant East End?
