The property contains a 'tala' tree, a native species that has survived on the grounds for over two centuries.
The house functioned as a military headquarters where San Martín planned the crossing of the Andes.
The estate was donated to the state in the early 20th century to be preserved as a public historical site.
The architecture follows the traditional 'chorizo' layout, typical of colonial homes designed for ventilation and natural light.
Archaeological excavations on the site have uncovered ceramic fragments and domestic items dating to the early 1800s.
Museo Pueyrredón is the former residence of Juan Martín de Pueyrredón, a key military and political leader during the Argentine War of Independence. Located in the Acassuso district of San Isidro, the museum preserves the colonial architecture and original layout of an 18th-century quintas, or rural estate. The property features a significant collection of artifacts, colonial-era furniture, and historical documents related to the independence movement. The site serves as a national historical monument and is maintained by the Municipality of San Isidro. Visitors can explore both the interior rooms and the expansive landscaped gardens, which provide views overlooking the Río de la Plata. The house was a strategic gathering point for figures like José de San Martín during the early 19th century. The museum hosts rotating cultural exhibitions and academic seminars regarding Argentine history. The physical structure remains one of the few authentic examples of late colonial residential construction in the Buenos Aires province.
