The Tower Bridge is a British bascule and suspension bridge. Its decorative facades are made of granite while the rest of the structure and foundation are made of typical steel and concrete. It is located close to the Tower of London for why they partly share its name.
The bridge is world-famous for its very special neo-gothic style architecture. It is composed of two large towers, a rigid suspension, a deck that opens to the passage of the tallest ships and, at the top, two parallel pedestrian footbridges. The machinery of the opening bridge has been open to the public since 1982 in the form of a museum showing the operation of the hydraulic mechanism that has been used since 1894 (date of the bridge's construction by Sir John Wolfe-Barry and Horace Jones) to lift the weighbridge.
