In 1955 naval aircraft strafed the Casa Rosada and other nearby buildings during the Revolución Libertadora, which toppled Juan Perón’s regime. On the northern side of the appropriately bureaucratic Ministerio de Economía, an inconspicuous plaque commemorates the attacks (look for the bullet holes to the left of the doors). The inscription translates as, ‘The scars on this marble were the harvest of confrontation and intolerance. Their imprint on our memory will help the nation achieve a future of greatness.’
