Why pilgrims come
Discover what makes Sacred Heart Mission at Coeur d'Alene's Old Mission State Park a place of pilgrimage
Idaho's oldest standing building, constructed from 1850 to 1853 through the combined work of Coeur d'Alene people and Jesuit missionaries and now interpreted within a state historic park.
Sacred Heart Mission is now a state-park historic church rather than an ordinary parish stop. Its deepest story is the encounter between the Coeur d'Alene people and Jesuit missionaries, expressed in a building made with Indigenous labor, local materials, and shared religious history.
