The Roosevelt Lodge Historic District comprises the area around the Roosevelt Lodge in the northern part of Yellowstone National Park, near Tower Junction. The district includes 143 buildings ranging in size from cabins to the Lodge, built beginning in 1919. The Lodge was first conceived as a field laboratory for students and educators conducting research in the park. It later became a camp for tourists, specifically designed to accommodate automobile-borne tourists. The Lodge is a simplified version of the National Park Service Rustic style.
