David Davis Mansion State Historic Site, 1000 Monroe Dr., was built in 1872 for U.S. Supreme Court Judge David Davis, Abraham Lincoln's campaign manager. The home is considered a fine example of mid-Victorian residential architecture; such features as indoor plumbing and a cast-iron cooking stove were considered luxuries. Original furnishings and other period pieces are enhanced by handsome woodwork and hand-painted ceilings. Guided tours of the mansion depart from the visitor center, which also offers an orientation video. The Prologue to Presidency: Abraham Lincoln on the Illinois Eighth Judicial Circuit exhibit in the Lincoln-era barn and a restored historic garden also are available.
