The Pirámide de Mayo (Spanish pronunciation: [piˈɾamiðe ðe ˈmaʝo]; English: May Pyramid), located at the hub of the Plaza de Mayo, is the oldest national monument in the City of Buenos Aires. Its construction was ordered in 1811 by the Primera Junta to celebrate the first anniversary of the May Revolution. It was renovated in 1856, under the direction of Prilidiano Pueyrredón. In 1912, after having undergone many modifications, it was moved 63 metres (68.9 yards) to the east, with the idea that a much larger monument would eventually be constructed around it. The monument is crowned by an allegory of Liberty, the work of the French sculptor Joseph Dubourdieu. From the ground to the peak of the statue's Phrygian cap, the Pyramid measures 18.76 metres (61.5 feet).

The headquarters of the Banco de Londres y América del Sur or Bank of London and South America in Buenos Aires was designed by Argentine architects Clorindo Testa and SEPRA (Santiago Sánchez Elía, Federico Peralta Ramos, Alfredo Agostini). 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 Clorindo Testa and SEPRA. 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.

The Revolution of 11 September 1852 was a conflict between the Province of Buenos Aires and the government of Justo José de Urquiza after the latter triumphed over Juan Manuel de Rosas at the Battle of Caseros. A period known as "National Organization" was initiated after the Battle of Caseros. Every political faction agreed on authorizing a national Constitution. However, in opposition to the rest of the country, the ruling upper class in Buenos Aires aspired to impose political requirements on the Argentine provinces, so as to maintain the traditional political and economic preeminence of the capital city. The result was a ten-year separation between the Argentine Confederation and the State of Buenos Aires. Both states claimed to be part of a single nation. But in reality, they behaved like separate states.

Buenos Aires City Hall (Spanish: Palacio Municipal de la Ciudad de Buenos Aires; lit. "Municipal Palace") was, until 2015, the seat of the Office of the Chief of Government of Buenos Aires, the capital city of Argentina. From its construction in 1914 to the reformation of the city's constitution in 1996, the building was the seat of the City Municipality. It faces the Plaza de Mayo, across from the Casa Rosada presidential palace, in the barrio of Monserrat. Since 2015, the Office of the Chief of Government has been located at a new building in the barrio of Parque Patricios. The City Hall still houses various government offices of the city government.

The Bombing of Plaza de Mayo was a massacre which took place in Buenos Aires, Argentina, on 16 June 1955. On that day, 30 aircraft from the Argentine Navy and Air Force strafed and bombed Plaza de Mayo square in Buenos Aires in the largest aerial bombing ever on the Argentine mainland. The attack targeted the adjacent Casa Rosada, the official seat of government, as a large crowd was expressing support for president Juan Perón. The strike took place during a day of official public demonstrations to condemn the burning of a national flag allegedly carried out by detractors of Perón during the recent procession of Corpus Christi. The action was to be the first step in an eventually aborted coup d'état. The number of identified bodies was put at 308, including six children; an unknown number of victims could not be identified.The disregard for civilian lives and the violence with which the act was carried out has prompted comparisons with the wave of state terrorism during the dictatorship of 1976-1983.
