The Cataldo Mission actually began in a different location near the St. Joe river. Due to frequent flooding, the missionaries moved to the current location near Cataldo, Idaho. This building was constructed using the raw materials available to the priests, and Indians who built it. They used massive trees, which they cut and shaped by hand, for the framework. The frame was held together with wooden pegs driven into aligned holes the workers hand drilled. They used smaller trees to fill in the spaces, and then used the wattle and daub technique with grass and mud for the finishing touch. The Priests, and Indians decorated the inside with huckleberries, tin cans, wood statues that were hand carved, old newsprint, and cloth from the Hudson Bay Company. The Cataldo Mission building was used for many years, and today, stands as Idaho's oldest building.
