Pruitt–Igoe was a large urban housing project first occupied in 1954 in the U.S. city of St. Louis, Missouri. Living conditions in Pruitt–Igoe began to decline soon after its completion in 1956.[3] By the late 1960s, the complex had become internationally infamous for its poverty, crime, and segregation. Its 33 buildings were torn down in the mid-1970s,[4] and the project has become an icon of urban renewal and public-policy planning failure.
