Chácara Tangará, Historic estate and park in Vila Andrade, São Paulo, Brazil

Chácara Tangará is a historic estate in São Paulo that now encompasses part of the public Burle Marx Park, combining native forest patches with cultivated gardens. The property features buildings designed by architect Oscar Niemeyer and demonstrates the collaboration between two major Brazilian designers.

Francisco Matarazzo Pignatari, known as Baby Pignatari, bought the rural estate in the 1950s and hired Oscar Niemeyer and Roberto Burle Marx to build a 3,000 m² house for Princess Ira von Furstenberg; the romance ended before completion. The unfinished house stood abandoned until the mid-1980s, when his only heir Giulio Cesare died and Lubeca S/A bought the 482,215.63 m² property in October 1986. CONDEPHAAT listed it in 1994.

The estate's name comes from the tangará bird, and the gardens were first laid out by Roberto Burle Marx for Baby Pignatari's planned mansion. In 1991 Burle Marx returned to rework them, while Rosa Kliass's office linked the garden to the environmental reserve, footpaths and leisure areas. The park also holds a Casa de Taipa e Pilão, a rammed-earth and pestle house tied to the Bandeirante era.

The site is best explored on foot, with pathways that connect different areas and allow for quiet moments in nature. Comfortable walking shoes are recommended, and visitors should allow time for slow exploration to fully appreciate both the forest sections and gardens.

The property protects two remaining patches of native Atlantic Forest with original vegetation from earlier times, having survived São Paulo's urban expansion. These rare remnants offer visitors a direct glimpse of the region as it existed before modern development.
