Built in the mid-17th century, it was listed by IPHAN and recognized as a world heritage site by UNESCO, the São Francisco Convent differentiates itself from other Franciscan complexes in the Brazilian Northeast, through the typology of the cloister's “mannery” columns and its mortars, containing in its composition clay of the local area.
