Stepney is a district of the London Borough of Tower Hamlets in London's East End that grew out of a medieval village around St Dunstan's church and the 15th century ribbon development of Mile End Road. The area built up rapidly in the 19th century, mainly to accommodate immigrant workers and displaced London poor, and developed a reputation for poverty, overcrowding, violence and political dissent. It was severely damaged during the Blitz, with over a third of housing totally destroyed; and then, in the 1960s, slum clearance and development replaced most residential streets with tower blocks and modern housing estates. Some Georgian architecture and Victorian era terraced housing survive in patches: for example Arbour Square, the eastern side of Stepney Green, and the streets around Matlock Street.
