The majestic 1903 sandstone Moss Mansion in Billings, at about 117,000 population (as of 2022), the largest city in the western state of Montana, located in the eastern, prairie-like part of the state far from mountainous towns to the west in the nation's fourth-largest state by area. Designed by New York City architect Henry Janeway Hardenbergh, the mansion was built by lumber baron and newspaper mogul Preston Moss and his wife, Martha. Photo by Carol Highsmith, 2022.
