Dr. Álvaro Guião State School, Secondary school in São Carlos, Brazil

Dr. Álvaro Guião State School occupies a two-storey eclectic building with art nouveau influence, inaugurated in 1916 on Rua Carlos Botelho. Its design is credited to German architect Carlos Rosencrantz, with engineer Raul Porto and builder Torello Dinucci. The main facade has curved volumes at the centre and ends, and a six-metre-wide granite staircase leads to the ground floor, which holds the hall, offices, library, amphitheatre and classrooms; the basement housed laboratories and rooms for physical education, manual work and painting.

Founded in 1911 as São Carlos Normal Secondary School, the institution was renamed in 1939 to honor education secretary Álvaro Guião. This change marked an important milestone in the school's development and its growing role in local education.

The school's name honors Álvaro Guião, the state education secretary who died in a plane crash in Ponte Nova in December 1939; the rename came by decree that same month. Its founding date, 22 March, is still celebrated as the school's anniversary, the day classes began in 1911.

The school stands on Rua Carlos Botelho, on the site of the former Capela de São Sebastião, with its main facade facing west within São Carlos's historic polygon. It is an active state school, so visits require prior arrangement with the administration and should avoid class hours. The 1916 building is in good condition and remains in educational use.

The cornerstone of the current building was laid on 18 September 1913 on the site of the old São Sebastião Chapel, and the school opened there on 18 November 1916. The project was by German architect Carlos Rosencrantz, built by engineer Raul Porto and master builder Torello Dinucci.
