Despite being little more than ten years old, the London Eye is one of the city’s most famous landmarks. Standing an impressive 443ft high, it’s the largest Ferris wheel in Europe, weighing over 2000 tons, yet as simple and delicate as a bicycle wheel. It’s constantly in slow motion, which means a full-circle “flight” in one of its 32 pods (one for each of the city’s boroughs) should take around thirty minutes: that may seem a long time but in fact it passes incredibly quickly. Book online (to save money), but note that unless you’ve paid extra you’ll still have to queue to get on. Tickets are also sold from the box office at the eastern end of County Hall.
