Museo Histórico Cornelio de Saavedra, History museum in General Paz Park, Buenos Aires, Argentina

The Museo Histórico de Buenos Aires Cornelio de Saavedra is a history museum housed in a 19th-century mansion in Buenos Aires, Argentina. It holds ten exhibition rooms across several floors, displaying furniture, weapons, silverware, and personal objects that belonged to figures from Argentina's past.

The museum opened on 6 October 1921 as the Museo Municipal de Buenos Aires, built on the collection of historical and artistic objects that Serviliano Ricardo Rafael Zemborain (1872-1912) left to the city in his will. It moved between several premises until 1941, when the chacra of Luis María Saavedra, nephew of Cornelio de Saavedra, was chosen as its home; architect Manuel Augusto Domínguez remodelled the house in the style of early 19th-century Buenos Aires quintas. It reopened there on 25 May 1942, was merged with the municipal museum in 1947, and gained two pavilions in 1955.

The museum's name honours Cornelio de Saavedra, president of the Primera Junta, and its grounds hold the chacra of his nephew Luis María Saavedra. Inside, the collection begun with Serviliano Ricardo Rafael Zemborain's bequest covers 19th-century daily life and politics, and includes history paintings by the French-born Argentine painter Léonie Matthis.

The building is located near Parque General Paz in the northern part of Buenos Aires and can be reached by bus. Since the rooms span several floors, picking up a floor plan at the entrance will help you find your way around without missing any section.

One of the historical cannons on the museum grounds inspired Argentine poet Baldomero Fernández Moreno to write a poem dedicated to it. It is rare for a museum object sitting outdoors to find its way directly into a country's literary tradition.
