Inaugurated in 2010, the Cosmococa Gallery features an architectural design by Arquitetos Associados. It houses a set of five spaces developed by Hélio Oiticica and Neville D'Almeida.
Built on uneven terrain, the building offers a dual perspective, according to the architects: from the lowest point it is like "a constructed stone artifact," but, when viewed from above, "the green roof is a continuation of the landscape with subtle orthogonal boundaries," blurring the lines between building and landscape. Internally, there is a space where there is no linearity or hierarchy between the exhibition rooms, leaving the viewer free to decide which work to visit.
