Which Brutalist bank building in Buenos Aires was designed by Clorindo Testa?

The Brutalist bank building in Buenos Aires designed by Clorindo Testa is the Bank of London and South America.

Designed by Testa with the Argentine firm SEPRA, the building was created after a competition organized by the bank around 1960. Construction began in 1962, and the headquarters opened in 1966 at the intersection of Reconquista and Bartolomé Mitre streets.

Its exposed concrete structure, deep shadows, projecting beams, and irregular openings make it a landmark of postwar Brutalism. Rather than hiding its structural system behind a conventional façade, the design turns the frame into the building’s visual identity. The location is also notable: it stands in Buenos Aires’s historic banking district, close to the Casa Rosada and surrounded by older Beaux-Arts buildings.

A common mix-up is between the bank and its building. The Bank of London and South America was a financial institution; the quiz answer refers specifically to its Buenos Aires headquarters, now associated with Banco Hipotecario.
