It is also tied to Colonel Mark L. McDonald, a financier who developed Santa Rosa's water works and streetcar system. The property has local recognition and was a filming location for Disney's \"Pollyana\".","narrative":"Mableton, also called the McDonald Mansion, is a large Victorian house at 1015 McDonald Avenue in Santa Rosa. A San Francisco financier built it in 1876 as the finest structure in the 160-acre McDonald Addition. The frame house rises well above its grounds, with a columned veranda on three sides, a paneled baronial entry hall with a skylight, eleven bedrooms, and a carriage house and gazebo nearby. Its design blends stick style, Gothic, Greek Revival and Galveston elements, and its large formal rooms were unusual for the North Coast. The nomination calls it probably among the largest houses of its style in California. It is also linked to Colonel Mark L. McDonald, who developed Santa Rosa's water works and horsedrawn streetcar system. The house later served as a setting for civic events and a Disney film. At the time of nomination it looked run down because of overgrown grounds, but inspections found it sound and restoration feasible.","period_of_significance":"19th Century","architect_builder":null,"architectural_style":"Victorian (stick style) with Gothic, Greek Revival and Galveston influences","criteria":[],"status_note":"Condition listed as deteriorated, mainly from overgrown landscaping; described as basically sound and unaltered, with restoration considered feasible.
