Tower Bridge is a famous landmark in London, England, and is one of the most recognizable bridges in the world. It spans the River Thames, connecting the City of London to the Southwark district. The bridge was opened in 1894 and is now considered a symbol of London, appearing in countless images and postcards of the city.

Tower Bridge was designed by Horace Jones and John Wolfe Barry, and its construction was a major engineering feat of the late 19th century. The bridge's two towers are made of Cornish granite and Portland stone, and they are connected by two walkways that offer stunning views of the river and city. The bridge's distinctive bascules, or lifting sections, can be raised to allow tall ships to pass through.

Tower Bridge is not only a working bridge, but also a popular tourist attraction. Visitors can take a tour of the bridge's two towers and learn about its history, engineering, and design, as well as admire the views from the walkways and exhibitions. The bridge's glass-floored high-level walkways, located 42 meters above the river, provide visitors with breathtaking views of the city and river.
