View of Tower Bridge from the Tower of London, 2004

Tower Bridge is a bascule bridge in London, over the River Thames. It is close to the Tower of London, which gives it its name. It is sometimes mistakenly called London Bridge, which is the next bridge upstream. The bridge is owned and maintained by Bridge House Estates, a charitable trust overseen by the Corporation of London.
