This massive red-sandstone mansion, built in 1901 for Billings banker Preston B. Moss, was designed by prominent New York architect Henry Janeway Hardenbergh. It has many European influences, including a Moorish entry, a Shakespearean library, and a French Louis XVI parlor. Oak and mahogany millwork gives an elegant feel to the upstairs bedrooms. The mansion, listed on the National Register of Historic Places, has been used in various TV miniseries and Hollywood films, and was featured on A&E's America's Castles in 1997. The Moss Mansion also hosts various events during the spring and summer months, and is elaborately decorated for Christmas. Moss Mansion has a monthly 3-4 hour Trunks and Treasures tour that includes refreshments for $25. The tour is an in-depth look at the home and the Moss family.
