The Oca is one of the four main buildings in Ibirapuera Park designed by Oscar Niemeyer for the 1954 Quadricentennial celebration.
The structure lacks internal load-bearing pillars, allowing for flexible exhibition layouts across its multi-level interior.
The name 'Oca' is a Tupi-Guarani term for the traditional longhouses used by various indigenous peoples of Brazil.
The building was designed to create a direct dialogue with the other modernist structures in the park, such as the Bienal Pavilion.
It has undergone multiple restorations to preserve the integrity of its concrete dome and natural lighting systems.
Oca is an exhibition space designed by architect Oscar Niemeyer, located within Ibirapuera Park in São Paulo. Its name refers to the communal dwellings of indigenous Brazilian tribes, which inspired its signature dome-shaped architecture. The building features an expansive, column-free interior that spans approximately 10,000 square meters. It functions as a venue for temporary art exhibitions, cultural displays, and national historical presentations. The structure is part of the architectural ensemble of the park inaugurated in 1954 to commemorate the city's 400th anniversary. Its central dome is constructed of reinforced concrete, reflecting Niemeyer's modernist style.

Check the official Ibirapuera Park website for the current exhibition schedule, as the venue closes between installations.
Wear comfortable walking shoes, as the interior involves significant floor space and circular ramp navigation.
Bring a light jacket as the massive concrete interior can feel significantly cooler than the outdoor park temperatures.
Do not attempt to visit without checking if a specific exhibition is currently open, as the venue often remains dark during installation periods.
Closed on Mondays for maintenance; often closed for several weeks between major temporary exhibitions.
