Azcuénaga's country house was built during the establishment of Buenos Aires in 1580 by Juan de Garay. After several generations it was inherited by Justa Rufina Basavilbaso, Azcuénaga's wife. Further generations of the family (with ancestry of the viceroy Antonio de Olaguer y Feliú as well) inherited it, until Carlos Villate Olaguer gave it to the Argentine state in 1913, to be used as an official residence of the President of Argentina. It was renamed as "Quinta de Olivos", and it was used by all Argentine presidents since Agustín Pedro Justo.
