Rosemount Museum

Built in 1893, this 37-room mansion was home to the John A. And Margaret Thatcher family and named for Mrs. Thatcher's favorite flower. It remained a family residence for 75 years. Designed by noted New York architect Henry Hudson Holly and two years under construction, the mansion was completed in 1893. Nearly all furnishings, accessories, decorative arts, paintings custom paneling, wall and window treatments are original to the home. See why Rosemount has been called Colorado's Crown Jewel, and why it was selected for showing on the A & E cable network's nationally televised America's Castle
