According to, the Missionaries introduced farming and animal husbandry along with Christian teachings to native populations in Montana.

Italian Father Anthony Ravalli, S.J. arrived in 1845. He was eager to embrace his assignment to serve among the Indian Tribes of the Rocky Mountain region. The beloved priest was Montana’s first physician, surgeon, and pharmacist with additional skills of an architect, artist, sculptor, and engineer.


St. Mary's was the first permanent settlement made by non-indigenous peoples in what eventually became the state of Montana. The original structure was renovated and rebuilt in 1866 and has been carefully preserved ever since.
