A kiva (also estufa) is a space used by Puebloans for rites and political meetings, many of them associated with the kachina belief system. Among the modern Hopi and most other Pueblo peoples, "kiva" refers to a large, circular, underground room used for spiritual ceremonies and as a place of worship.
