Presidio Santa Cruz de Terrenate

Located in the San Pedro Riparian National Conservation Area (SPRNCA), Presidio Santa Cruz de Terranate is the most well-preserved defensive Spanish site in a broader regional network. A stone foundation and adobe wall fragments mark the location of this isolated and dangerous military outpost. An interpretive trail guides you around the site.

Established in 1775 by Hugo O’Conor, an Irish-born Spanish Army Colonel, the Presidio served as a strategic outpost. It was used during conflicts between Spanish forces and Apache groups, and to fend off Russian and French incursions. Persistent Apache resistance, corruption within the Spanish administration, and declining soldier morale led to incomplete construction.

S. Army about a century later. Archaeologist Charles DiPeso studied the site in 1951.

He suggested it was built atop the precontact Sobaipuri village of Quiburi. Subsequent research confirmed an earlier settlement beneath the Presidio. It was not the renowned Quiburi village but was used by Sobaipuri, Hohokam, and Archaic peoples over time.

The structures were made of adobe on stone foundations, and only the bases of walls remain visible. The adobe walls are capped annually with a fresh coat of adobe mud by organized volunteer projects. Read a story on our blog about how "mud parties" help improve the longevity of this site.
