Tower Bridge, London

Only a handful of bridges around the world have achieved iconic status, and Tower Bridge is one of them. Judging by its name and appearance, you might think the bridge is an original part of the adjacent Tower of London. Its construction, however, was completed in 1894, centuries after the fortress. Head into one tower and up to the walkway 42 m (138 ft) above the River Thames to reach the other tower. You'll have a panoramic view of the city along the way. Stop by the exhibit in the east walkway to watch a video about the bridge's construction, and to see a gallery of photos of 20 significant bridges around the world. Head into the Victorian engine rooms, where you can experience a recreation of the motor-based operation of the bridge at the time of its inauguration and view a virtual bridge-lift. If your visit to the area will be near dusk, stop to see the bridge lit up. Plan my London trip by asking Inspirock to come up with tips and suggestions.
