The São Paulo Museum of Art (Portuguese: Museu de Arte de São Paulo, or MASP) is an art museum in São Paulo, Brazil. It is well known for the architectural significance of its headquarters, a 1968 concrete and glass structure designed by Lina Bo Bardi. It is considered a landmark of the city and a symbol of modern Brazilian architecture.
The museum was founded in 1947 by Assis Chateaubriand and Pietro Maria Bardi, and is maintained as a non-profit institution. MASP distinguished itself by its involvement in several important initiatives concerning museology and art education in Brazil, as well as for its pioneering role as a cultural center. It was also the first Brazilian museum to display post-World War II art.
