Tumacácori is the site of a Franciscan mission established in the late 18th century along the Santa Cruz River in what is now southern Arizona. The mission was eventually abandoned and never rebuilt. Today, its remains are preserved as part of Tumacácori National Historical Park.

Long before European settlement, the Santa Cruz Valley was home to the O’odham people. They cultivated crops such as corn, beans, squash, and cotton, and built dome-shaped dwellings from saplings, brush, and mud. Life here was closely tied to the land and the seasonal flow of water.

In 1691, Jesuit missionary Eusebio Francisco Kino established the first mission in the region among the O’odham. Following an uprising in 1751, the original settlement was abandoned and later relocated closer to a Spanish military outpost.

A small church was completed by 1753, but in 1767 the Jesuits were expelled from Spanish territories by order of King Charles III. Franciscan friars assumed control the following year. They faced ongoing challenges: resistance from converts, Apache raids, disease, limited resources, and little government support.

In 1800, construction began on a larger church intended to reflect the Baroque style of Mission San Xavier del Bac. Due to lack of funding, the structure was never completed. By 1848, the mission was fully abandoned and left to deteriorate.

Preservation efforts began in 1908, when President Theodore Roosevelt designated Tumacácori a National Monument. In 1990, it became part of Tumacácori National Historical Park.
