The headquarters of the Banco de Londres y América del Sur or Bank of London and South America in Buenos Aires was created in 1959 by Argentine architect Clorindo Testa. It is located in San Nicolás.
In 1959, a design contest was announced the project by the Bank of London and South America. The land was located on a street corner in the Buenos Aires CBD, an area housing nearly half the nation's financial activity. The winning design was submitted by the Clorindo Testa team, associated with SEPRA, a society composed of architects Sánchez Elía, Peralta Ramos and Agostini.
The project's architectural approach was among the most far-reaching and well-known local contributions to international architecture of the 1960s, as well as the country's most easily-identifiable example of Brutalist architecture.
The building, completed in 1966, was occupied by the local Lloyds Bank branch during the 1980s and early 1990s, and in 1997, was acquired by the newly-privatized Banco Hipotecario.
