The wheel was meant to be operational in time for the millennium celebrations – unfortunately for technical reasons, it wasn’t open until mid 2000. It is now open and you can ride in a pod (Admission charge).
County Hall, the large “Edwardian style” building overlooking the Thames near the London Eye, was opened in 1922. Though now housing a hotel, a Dali museum (Dali Universe), the Saatchi Gallery and the London Aquarium, it was the home of London government until 1986.
See it on the cultural walk and bridges walk.
