Whilst contemplating what to see next in London, I came across the website for the Tower Bridge Exhibition, and thought that it would be a good place to take photographs of the city, if nothing else. The entrance is at the North West Tower of the Bridge and admission costs £8 for adults. It was a lot busier than I was expecting, but the queue moved along very smoothly – clearly the staff are used to big crowds. You head up to the walkway in a lift and then view a presentation with a (vaguely amusing) video portraying Queen Victoria in conversation with the architects who designed the Bridge. You can then continue on your way to the actual walkway in order to admire the views from 42 meters above the River Thames.
