Oga Pysy’s are traditional Guarani and Kaiowá ceremonial houses, that offer important spaces for seasonal rites, and social harmony, and provide a direct link to their central deity, Nhanderu Tupã. In a context of ecosocial genocide perpetrated by Brazil’s fascist government and the large-scale agribusiness operations in Guarani and Kaiowá territory, Oga Pysy’s have been also been an important site of resistance through cultural production. Only around 20 ceremonial houses exist due to arson attacks.
