The site where Tumacácori National Historic Park now stands was visited by missionary Father Eusebio Francisco Kino in 1691, but the Jesuits didn't build a church here until 1751. You can still see some ruins of this simple structure, but the main attraction is the mission of San José de Tumacácori, built by the Franciscans around 1799-1803. A combination of circumstances—Apache attacks, a bad winter, and Mexico's withdrawal of funds and priests—caused the remaining inhabitants to flee in 1848. Persistent rumors of wealth left behind by both the Franciscans and the Jesuits led treasure seekers to pillage the site; it still bears those scars. The site was finally protected in 1908, when it became a national monument.
Information about the mission and the Anza trail is available at the visitor center, and guided tours are offered daily (more in winter than in summer). A small museum displays some of the mission's artifacts, and sometimes fresh tortillas are made on a wood-fire stove in the courtyard. In addition to a Christmas Eve celebration, costumed historical high masses are held at Tumacácori in spring and fall. An annual fiesta the first weekend of December has arts and crafts and food booths.
