La Citadelle du Loisir, Sao Paulo's Pompeia Social Center

In Sao Paulo's Palmeiras district, a former factory aligns its early 20th-century workshops with strange concrete blocks that face the city and its towers. It's a social and cultural center for commercial workers. Its architect, Lina Bo Bardi, prefers to speak of a "citadel of leisure", a symbol of both the reconversion of a workplace and the affirmation of an alternative to the metropolis. A major work of Architettura Povera.
