Coeur d'Alene's Old Mission State Park, off I-90 exit 39, is named for the restored Old Sacred Heart Mission, built 1848-53 by Coeur d'Alene Indians under the guidance of Jesuit priest Father Antonio Ravalli. It is reputedly the oldest standing structure in the state. The 18-inch-thick mission walls were built of woven grass and adobe mud without nails. The Sacred Encounters exhibit documents the meeting of the Jesuit missionaries and the Coeur d'Alene and Salish tribes and the effects the encounter had on both cultures.
Video presentations, mission tours and a visitor center are available. The park also is the headquarters for the state-run portion of the Trail of the Coeur d'Alenes; the 56-mile section runs between Mullan and Harrison.
Pet friendly (call for restrictions/fees.). Recreational activities are permitted. Picnicking is permitted.
