London's Tower Bridge is one of the most recognizable bridges in the world. Its Victorian Gothic style stems from a law that forced the designers to create a structure that would be in harmony with the nearby Tower of London.
Taking photographs of the Tower bridge is a favorite London tourist activity, but you can also go inside the bridge, where you'll have a magnificent view over London from the walkway between the two bridge towers.
Inside the bridge is the Tower bridge Exhibition, a display area that encompasses the walkway and the two famous towers where you can observe the Victorian engine room. Visitors can learn about the history of the bridge via photos, films, and other media.
