When you first step into the entry way of this magnificent building, notice the beveled glass windows, ornate wrought iron, sandstone and vaulted brick ceiling. A free-standing spiral staircase inside is surrounded by 26 rooms adorned with exotic woods from around the world, several stained glass windows, hand-painted wallpaper by Marshall Field, and a redwood paneled 4th floor ballroom. Thousands of historic artifacts are on display in the museum including textiles, books, vintage clothing and accessories. The furniture collection here is on permanent loan from the University of Montana.

Inside the mansion are four fine art galleries featuring works by local, regional and national artists.
