The Buenos Aires Botanical Garden beckons you. Enveloped within 17.25 acres are over 5,000 species of plants. They are nestled into sections resembling Asian, French, African, Roman and American garden styles. This Art Nouveau greenhouse is the largest of five on the estate. The splendid environment was designed by Carlos Thays in the 1890s. He is the same talented landscape architect who shaped the largest park in Buenes Aires: Parque Tres de Febrero.
