[2] A will left by a local heiress, Petronila Rodríguez de Rojas, stipulated that her roughly 6 hectares (15 acres) lot in uptown Buenos Aires be used for an educational and charitable compound to include a church, an old-age asylum and a girls' school for no less than 700 pupils.
Work began in 1886[3] on the building which, per Mrs. Rojas' wishes, would include extensive museum and library facilities, as well.
The building's location facing leafy Rodríguez Peña Plaza created an urban oasis in the otherwise bustling Barrio Norte section of the upscale Recoleta ward.
A lot immediately to the south of the building was converted into Petronila Rodríguez de Rojas Plaza (a playground) as a belated homage to the civic-minded lady during the 1950s (as was a primary school in the Parque Chas neighborhood, in 1934).
Still officially known as the Sarmiento Palace, the building is popularly known as the Pizzurno Palace for the side street built facing it, which was renamed in honor of pedagogian and local primary school system pioneer Pablo Pizzurno, following his death in 1940.
