Moss Mansion Historic House Museum

The mission of the Billings Preservation Society, symbolized by the Moss Mansion, is to inspire, to educate and to facilitate historic and cultural preservation activities for our community and for its future generations.

In 1903, entrepreneur Preston Boyd Moss (better known as "P.B.") built the Moss Mansion, greatly influencing the culture of Billings, Montana.

Designed by New York architect, Henry Janeway Hardenbergh, designer of the original Waldorf Astoria and Plaza Hotels, the mansion showcases inspired architecture, unrivaled craftsmanship and exquisite décor. The mansion is listed on the National Register of Historic Places and has graced the silver screen on several occasions as the perfect site for period films such as Son of the Morning Star and Return to Lonesome Dove.

Although the youngest daughter, Melville Moss, resided in the home until the mid-80’s, the house and its original fixtures remain intact. Modern day visitors marvel at the home’s amenities which include a call button system for the servants, among other impressive feats of technology for the period. The home not only records the activities of early Billings development but also interprets the inner workings of the family through letters shared among its members.
