is a combined bascule and suspension bridge in London, built between 1886 and 1894. The bridge crosses the River Thames close to the Tower of London and has become an iconic symbol of London. As a result, it is sometimes confused with London Bridge, about half a mile (0.8 km) upstream. Tower Bridge is one of five London bridges owned and maintained by the Bridge House Estates, a charitable trust overseen by the City of London Corporation. It is the only one of the trust's bridges not to connect the City of London directly to the Southwark bank, as its northern landfall is in Tower Hamlets.
