Moinho Matarazzo, Industrial building in Brás District, São Paulo, Brazil

Moinho Matarazzo is a long industrial building at the corner of Rua Monsenhor Andrade and Rua do Bucolismo in São Paulo's Brás district. Its pale grey-white brick facade rises above a dark, stained lower wall, with tall narrow arched windows in vertical columns, some dark and some boarded. Black metal balconies project from several central bays, and the range ends in a pointed gable.

The building was established around 1900 by Francesco Matarazzo as part of a major industrial enterprise that shaped Latin America's economy. It played a key role in developing São Paulo as an industrial center during the early decades of the 20th century.

The mill's name recalls Francesco Matarazzo, the Italian immigrant who arrived in Brazil in 1881 and founded it in 1900. Its workers staged some of São Paulo's first strikes: in 1907 a committee demanded higher wages and shorter hours, was refused, and the mill stopped. The pale grey-white brick facade above the dark, graffiti-marked lower wall is what visitors see today.

The mill stands at the corner of Rua Monsenhor Andrade and Rua do Bucolismo in the Brás district, not near Anhangabaú station. The site lies close to the old São Paulo Railway line, whose freight access shaped the location. The building is a protected landmark, so visits are to its exterior; the lower wall carries red graffiti and some upper windows are boarded.

Its position next to São Paulo Railway allowed the mill to import wheat directly from Argentina and the United States, giving it a major advantage. This rail connection was crucial to its operations and profitability during its working years.
