The Wendell O. Pruitt Homes and William Igoe Apartments, known together as Pruitt–Igoe (/ˈpruːɪt ˈaɪɡoʊ/), were joint urban housing projects first occupied in 1954 in St. Louis, Missouri, United States. The complex of 33 eleven-story high rises was designed in the modernist architectural style by Minoru Yamasaki. At the time of opening, it was one of the largest public housing developments in the country. It was constructed with federal funds on the site of a former slum as part of the city's urban renewal program. Despite being legally integrated, it almost exclusively accommodated African Americans.
Although initially viewed as an improvement over the tenement housing it replaced, living conditions in Pruitt–Igoe began to deteriorate soon after completion. By the mid-1960s it was plagued by poor maintenance and crime, particularly vandalism and juvenile delinquency. Numerous initiatives to reverse the decline failed, and by 1970 more than two-thirds of the complex was vacant. Demolition of the complex began in 1972 with a televised implosion of several of the buildings. Over the next four years, the rest of the complex was vacated and demolished.
