Dominating the Plaza de Mayo, the Casa Rosada - or pink house - is the seat of the Argentine national government and houses the president's office. Witness to much of the city's history, it was from the balconies of the Casa Rosada that Juan and “Evita” Perón addressed the masses during the late 1940s and early 1950s. The central archway was designed by Italian architect Francisco Tamburini, who was also responsible for the original design of the Colón Theatre, and was completed in 1890. https://turismo.buenosaires.gob.ar/en/otros-establecimientos/casa-rosada
