Ilê Axé Iyá Nassô Oká is a historic Candomblé temple (or terreiro, in Portuguese) in the city of Salvador, Bahia, in northeastern Brazil.

Located on a hill above Vasco da Gama, a busy avenue in the working-class neighborhood of Engenho Velho, the terreiro belongs to the Ketu branch of Candomblé, which is heavily influenced by the religious beliefs and practices of the Yoruba people.

Recently uncovered historical evidence shows that at its incept the new community operated out of a townhouse that she and her husband owned in the Pelourinho district, in the center of the city.

A few years later, following a major slave uprising in 1835, in which her sons were accused of participating, Iyá Nassô along with her family and other members of her household, including several former captives, returned to Africa.

Iyá Nassô remained there, but in 1839, one of the women who had accompanied her, Marcelina, went back to Bahia, where she assumed leadership of the religious community, a position she held until her death in 1885.

[9] Both grew into renowned temples in their own right and like Ilê Axé Iyá Nassô Oká itself are now recognized as national historic heritage sites.

[14] In the early 1980s, urban expansion led to real estate speculation, threatening the very existence of Ilê Axé Iyá Nassô Oká.

This was followed in August 1986 by another, even greater precedent: historic heritage status from the National Institute of Historic and Artistic Heritage (IPHAN), which included not only the building where public ceremonies are held but "the entire site, an area of approximately 6,800 m2, with the buildings, trees and main sacred objects, accompanied by all necessary measures that effectively guarantee the safety of this property.

"[15][12][16] This permitted the temple to regain control over the land where the gas station had been constructed and gave rise to the renovation project designed by Niemeyer, described above.
