The need for a new central post office in Buenos Aires was first raised in 1888 by the director of the Correo Argentino (Argentine Postal Service) at the time, Dr. Ramón J. Cárcano.

Spolsky reengineered the design, which featured masonry supports, to consist of a steel-reinforced concrete structure, for which 2,882 steel pillars were placed onto the bedrock, 10 m (33 ft) deep.

[14] Limitations on the city's public works budgets resulting from the onset of World War I forced another major design alteration in 1916.

Spolsky achieved this without substantial changes to the building's exterior, though the number of delays led to considerable cost overruns on the project, and its budget was exhausted in 1923.

[9] The central hall was decorated with marble throughout, features stained glass windows, numerous bronze sculptures and mail drop boxes, and a four-story-high domed ceiling.

Opposition to the 1979 sale of the parking lot for the construction of a local Bank of Tokyo headquarters proved insurmountable, and the plans were cancelled.

[16] Completion of the new centre was delayed considerably, however, and in 2012 its designated name was amended as Centro Cultural del Bicentenario Presidente Dr. Néstor Carlos Kirchner.

[9] When the architects added new spaces and elements, they purposely used different materials such as clear and frosted glass and stainless steel, to maintain sight of the ornate Beaux-Arts style beauty of the original building.

[9][17] Since the inauguration of President Mauricio Macri (whose father, Francisco Macri, led a conglomerate that once owned the building),[18] the Centre became part of the newly formed Federal System of Media and Public Contents (Sistema Federal de Medios y Contenidos Publicos) and has sought to de-emphasize its function as a homage to Néstor Kirchner.

[23][24][25] Two months later, the government revealed that the building would be renamed "Palacio Libertad",[26] after considering other names such as Julio Argentino Roca, Jorge Luis Borges, Domingo Faustino Sarmiento, and Bartolomé Mitre.

[27] On 10 October 2024, the national government officialised the change of name to "Palacio Libertad, Centro Cultural Domingo Faustino Sarmiento".
