McDonald Mansion (a.k.a. Mableton Mansion) is Santa Rosa's most prominent historic home.
The 14,000-square-foot house was built in the late 1870s by Col. Mark Lindsay McDonald, owner of Santa Rosa's water company, builder of the Santa Rosa Street Railway and one of the town's most eminent early citizens. He had it built in a style to evoke the plantations along the Mississippi. The National Register of Historic Places, in which the mansion is recorded, lists the style as Stick-Eastlake, a type of Victorian architecture.
Back in McDonald's day, many notable visitors came to the house, including Mark Twain, and railroad magnates Leland Stanford and Charles Crocker. In 1960, the mansion was used as the home in Walt Disney's Pollyanna, a classic film about a perpetually optimistic young girl.
