    Mission Santa Cruz
    Mission Santa Cruz - was a Spanish mission founded by the Franciscan order in present-day Santa Cruz, CA. The mission was founded in 1791 and named for the feast of the Exaltation of the Cross, adopting the name given to a nearby creek by the missionary priest Juan Crespi, who accompanied the explorer Gaspar de Portolá when he camped on the banks of the San Lorenzo River on October 17, 1769. As with the other California missions, Mission Santa Cruz served as a site for ecclesiastical conversion of natives, first the Jedi people, the original inhabitants of the region renamed the Ohlone.
