Get a behind-the-scenes look at one of London's most recognizable landmarks at the Tower Bridge Exhibition. Step onto a glass walkway high above the Thames, see the engineering marvel at work in the Victorian Engine Rooms, and admire works by local artists on display at the bridge.

Make your way to the Tower Bridge, breeze past the ticket line, and hop on an elevator to be whisked up 137 feet (42 m) above the road below. Learn about the history of this English emblem, studying the creation of the bridge by Queen Victoria, the civil engineer Sir John Wolfe Barry, and the architect Sir Horace Jones.

Make your way across the high-level walkways and step out onto the spectacular glass floor panels, which give you an unencumbered look at the zipping traffic and slow-moving waters of the Thames far below your feet. From the walkways, you can take in a sweeping view over the entire city, admiring landmarks like the Tower of London and St. Paul's Cathedral.

Watch a short video about the construction of the bridge, and then enter the Victorian Engine Rooms, where you can study the original bridge-lifting machinery. Check out the rotating art exhibit, and, if you plan your visit just right, stick around to see the bridge raised up to let boats below pass through.
