Explore upstairs and downstairs life in St. Paul’s largest house. Built for railroad titan James J. Hill, this 36,000-square-foot Gilded Age mansion was once the largest private residence in the state. With 13 bathrooms, 22 fireplaces, 16 chandeliers, a reception hall nearly 100 feet long, sophisticated technical systems, and a two-story, skylit art gallery, the house was a symbol of success, personal taste, and family life. Guided tours of the James J. Hill House are offered Thursday–Sunday. Throughout the year enjoy signature events and themed tours.
