Tower Bridge is one of London’s most famous landmarks, built between 1886 and 1894 as a combined bascule and suspension bridge across the River Thames. Its twin Gothic‑style towers are connected by high‑level walkways and house the hydraulic machinery that once lifted the bascules to let tall ships pass. Located next to the Tower of London, it quickly became an icon of Victorian engineering and a symbol of the city. Today visitors can walk across the bridge for free or explore the Tower Bridge Exhibition inside the towers to see the engine rooms and enjoy glass‑floored walkways with views over the river.
