St Louis modernist housing project demolished only 16 years after opening — its destruction in 1972 became the symbolic 'end of modernism' in architecture.
From Wikipedia
The Wendell O. Pruitt Homes and William Igoe Apartments, known together as Pruitt–Igoe, 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.
