Saldanha Marinho Building, Art Deco building in Sé district, São Paulo, Brazil.

The Saldanha Marinho Building occupies a triangular block at Rua Líbero Badaró 39, near Largo São Francisco, with rounded corners suited to the wedge-shaped lot. Its facades are clad in stone-dust mass that gives a shimmering surface, and the interior has high ceilings, large iron-and-glass window frames and a marble floor with geometric patterns in the elevator hall. The top is set back with terraces and openings.

The building was designed by Elizário da Cunha Bahiana for the São Paulo Automobile Club, with a structure by Cristiano Stockler das Neves that won an architectural competition. The Paulista Railway Company acquired the unfinished project and completed it in 1933, keeping the stained glass by Casa Conrado and the ticket counters. It was listed by Condephaat in 1986.

The building showcases early Art Deco style and stands as an important example of this movement in Brazil. Its characteristic geometric forms and curved lines are clearly visible from street level.

The building occupies a triangular block at Rua Líbero Badaró 39, near Largo São Francisco, with rounded corners facing the streets. It is the seat of the State Secretariat of Public Security, so the interior is not open to visitors; the facade, the marble-and-glass entrance hall details and the railway ticket counters are best seen from the street. The Condephaat listing dates from 8 September 1986.

The building now houses offices for the State Secretary of Public Security, though it was originally designed as a gathering place for automobile club members. This repurposing shows how historical structures in the city have adapted to serve different functions.
