Quinta Los Ombúes, Colonial house museum in San Isidro, Argentina.
Quinta Los Ombúes is a colonial-style mansion in San Isidro built in 1760, featuring white walls, a central courtyard, and an old water well as its main architectural elements. The property includes spacious gardens with native ombú trees scattered throughout, creating distinct outdoor areas on the grounds.
The estate was built in the second half of the 18th century and reflects the architecture and household life of wealthy families in Buenos Aires during that period. It was later designated a national historical monument to preserve its role in documenting colonial Argentina's past.
The estate is named after the native ombú trees that dominate its grounds, and these plants remain central to how the property looks and feels today. Visitors can observe how the landscape reflects the agricultural traditions of colonial Argentina.
The museum is accessible to visitors through guided tours that lead through the house and its rooms with explanations provided. A visit is best planned during regular opening hours and does not require any special preparation or equipment.
The house is linked to Mariquita Sánchez de Thompson, who lived here as a child; in 1805 she defied her family by marrying her cousin Martín Jacobo Thompson against their wishes, a case that reached the courts and viceregal authorities. The episode is remembered as one of the first marriages in Buenos Aires celebrated against parental consent.
