Tower Bridge, spanning the River Thames in central London, is one of the city’s most recognizable landmarks. Opened in 1894, it combines a bascule and suspension bridge design, allowing ships to pass while connecting the historic areas of Tower Hamlets and Southwark. Beyond its practical role, Tower Bridge is a major tourist attraction, featuring a glass-floored walkway and exhibition detailing its engineering and history. It continues to symbolize London’s architectural innovation and heritage.
