Old Mission State Park

Coeur d'Alene's Old Mission State Park is a heritage-oriented state park in North Idaho, preserving the Mission of the Sacred Heart, or Cataldo Mission, national historic landmark. The park contains the church itself, the parish house, and the surrounding property. Built 1850–1853, Mission of the Sacred Heart is the oldest standing building in Idaho. It was designated a National Historic Landmark in 1961, and put on the National Register of Historic Places in 1966.
In 1831, the Nez Perce Indians and Flathead Indians had heard of the white man's Book of Heaven and wanted more information. They sent six men east to St. Louis with four arriving, and in 1842, Father Pierre-Jean De Smet responded to the request and came to the area. Fr. Nicholas Point and Br. Charles Huet came and helped to pick a mission location. The first chosen was along the St. Joe River and was subject to flooding. In 1846, they moved it to the current location.
