Over 50,000 objects document Argentina's May Revolution and wars of independence through the real possessions of the people who made them — portions of the collection donated by descendants of key figures. The building itself adds texture: an English merchant's mansion, enlarged by a Rosas ally in the 1840s, then sold off after that ally fled into exile, and eventually converted into the museum by the city in 1897.
What to look for
- Regalia, documents, and personal belongings of José de San Martín and Manuel Belgrano, with some items sourced from family donations
- Personal effects and furnishings connected to Juan and Eva Perón
- The mansion's fabric — built for English merchant Daniel Mackinlay, later expanded by American businessman Charles Ridgley Horne in the 1840s
Located in the San Telmo ward; Lezama Park surrounds the building and is worth a walk after your visit.
