The Set of Old Installations of the Polytechnic School is a block of six heritage-listed buildings facing Tiradentes metro station, bounded by Praça Coronel Fernando Prestes, Avenida Tiradentes, Rua Afonso Pena and Rua dos Bandeirantes.

Today they house FATEC, the Centro Paula Souza, the São Paulo Historical Archive and ETESP.

The Polytechnic School of São Paulo was founded on 15 February 1894, during Bernardino José de Campos Júnior's state government, to train engineers for the city's urbanisation. Its first home was the Palacete do Marquês de Três Rios, built in 1860 and demolished in 1929. The Paula Souza Building, the oldest purpose-built structure, opened in January 1899; the Ramos de Azevedo Building followed in 1920 and the Rodolfo Santiago in 1944. The school joined the newly created University of São Paulo in 1934 and began moving to the Cidade Universitária in 1960.

The buildings hold collections that document how technical education developed in São Paulo over time. Visitors can observe how engineering studies and teaching methods changed through different periods.

The archive and library are accessible on weekdays for those wanting to view the collections. Special arrangements can be made for research purposes or extended visits.

The Paula Souza Building, the oldest in the complex, opened in January 1899 and was named after Antônio Francisco de Paula Sousa, the school's first director. It was the first structure built specifically for the Polytechnic School, designed by Ramos de Azevedo's office to house its general laboratories.
