Architecture Near Tower Bridge, London

London Bridge refers to several historical bridges that have spanned the River Thames between the City of London and Southwark, in central London. The current crossing, which opened to traffic in 1973, is a box girder bridge built from concrete and steel. This replaced a 19th-century stone-arched bridge, which in turn superseded a 600-year-old medieval structure. This was preceded by a succession of timber bridges, the first built by the Roman founders of London. The bridge is the subject of the popular nursery rhyme London Bridge Is Falling Down. The current bridge stands at the western end of the Pool of London but is positioned 30 metres  upstream from previous alignments. The traditional ends of the medieval bridge were marked by St Magnus-the-Martyr on the northern bank and Southwark Cathedral on the southern shore. Until Putney Bridge opened in 1729, London Bridge was the only road-crossing of the Thames downstream of Kingston-upon-Thames. The modern bridge is owned and maintained by Bridge House Estates, an independent charity overseen by the City of London Corporation.  Source
