The Riordan Mansion is a historic building, built by two lumberjack brothers in 1904. It’s conveniently located in the heart of Flagstaff, practically on NAU campus. Sabrina was given a beautiful room to get ready, and the grounds of the mansion were a dream to film. The most memorable moment was when Sabrina and Tate’s pups barked in approval during their ceremony kiss. Preview above, and the full film has been kept private per the couple’s request.
