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.
