Moss Mansion
A largely intact Preston Boyd Moss family home reveals architecture, domestic labor, technology, taste, and the uneven wealth of early Billings.

Artwork inspired by Gennie DeWeese
Moss Mansion preserves far more than an elegant 1903 interior. Designed by Henry Janeway Hardenbergh for Preston Boyd Moss and his family, its original furnishings, textiles, fixtures, and early household systems show how wealth generated through banking, utilities, agriculture, and civic development was translated into a public statement in rapidly growing Billings.
The service spaces prevent the formal rooms from becoming a simple design tour. Kitchens, circulation routes, storage, and the practical labor of maintaining the house reveal who made its comfort possible. Standard tours last about an hour, but the historic building has a serious access limit: every exterior route to the first floor includes steps and there is no ramp or lift.
