Escola Estadual de Primeiro Grau Campos Salles, Public elementary school in Liberdade District, São Paulo, Brazil

Escola Estadual de Primeiro Grau Campos Salles is a school building in São Paulo featuring a two-story structure with H-shaped classroom layouts. The construction combines marble accents with traditional clay brick methods and received heritage protection from both CONDEPHAAT and Conpresp due to its architectural and educational merit.

The building was founded in 1911 as part of São Paulo's government education initiative during Brazil's First Republic era. It was one of approximately 170 school buildings constructed at that time to expand the public education system.

The school reflects European neoclassical design that shaped São Paulo's early public education landscape. Its marble details and brick construction became characteristic of the neighborhood's architectural identity.

The building stands on Rua São Joaquim, a short walk from São Joaquim station on metro Line 1-Blue. It has been closed since the 1992 fire and is not open to visitors; the structure is fenced off and in poor condition, so it is best seen from the street. The remaining lot measures 1,523 square metres.

The fire of 31 December 1992 was set by four former pupils who said they were taking revenge for injustices suffered at the school. It destroyed mainly the roof, ceilings and floors, leaving the building at risk of collapse; the students were transferred to neighbouring schools. After the fire, the intruders' clothes were hung on a line at the back of the yard.
