Sesc Pompeia is a cultural and sports centre in the working-class Pompeia district of São Paulo. It was a factory, opened in 1938, that made oil drums and later refrigerators, and the architect Lina Bo Bardi converted it between 1977 and 1986 for the non-profit Sesc; it is now one of Brazil's best-known brutalist buildings. Bo Bardi kept the factory buildings and stripped out their inner walls to make open halls for reading, exhibitions and theatre, moved the sports facilities into two concrete towers pierced by irregular, organic windows, and linked them with eight aerial walkways. Entry and most exhibitions are free, Tuesday to Saturday 10:00-22:00 and Sunday 10:00-19:00, closed Mondays. Free guided heritage tours of the building run on Wednesdays at 11:00, 14:00 and 16:00, Thursdays at 15:00, 17:00 and 19:00, and weekends and holidays at 11:00, 14:00 and 16:00.
