Mariano Acosta school, Normal school in Balvanera, Argentina

Mariano Acosta school at General Urquiza 277 combines architectural elements from the late 1800s with an additional wing added in 1944. The main building displays the style of that period, while the newer section expanded the school to serve more students.

The school was founded in 1874 and first operated in Casa de Cambaceres before relocating to its current location in 1889. This move marked a turning point as it established itself as a teacher training institution.

The school's name honours Mariano Acosta, governor of Buenos Aires when the founding bill was drafted in 1873; President Marcelo Torcuato de Alvear, an alumnus, gave the school that name in 1924 for its 50th anniversary. Its alumni include writers Julio Cortázar and Leopoldo Marechal, composer Enrique Santos Discépolo, actor Ricardo Darín and rapper Wos.

The school is an active public institution at General Urquiza 277, in Balvanera, and its classrooms are not open to tourists; the yellow facade and the "ESCUELA NORMAL DE PROFESORES" inscription are best viewed from the street. The building was declared a National Historical Monument in 1999, so check with the school or the city's heritage office about occasional guided visits.

The building received National Historical Monument status in 1999 through Argentine law 25.171. This recognition honored its role in shaping the country's educational history over more than a century.
