Mission Puerto de Purísima Concepción

Mission Puerto de Purísima Concepción was a Spanish colonial settlement built where the Colorado River crossed major trade routes connecting distant regions. The site reveals remnants of traditional Spanish colonial design combined with construction techniques adapted to the local landscape and materials.

Father Francisco Garcés founded the settlement in October 1780 as part of Spain's effort to establish a land route linking Sonora with Alta California. The establishment faced immediate resistance in this region where established populations were unwilling to accept the new presence.

The mission served as a meeting place where Spanish religious teachings encountered the existing ways of the Quechan people who lived along the river. Today, standing at this location helps visitors understand how two different worlds intersected in this remote area.

The historical marker is located on Picacho Road in Fort Yuma, about a mile south of Winterhaven Road, and is accessible by vehicle. Visitors should note that the location is remote and it is wise to check local conditions before traveling to the site.

The settlement was destroyed in July 1781, just nine months after its founding, making it one of the shortest-lived Spanish colonial efforts in the region. This rapid end shows the deep conflicts between colonial ambitions and the local resistance they encountered.
