Along with the impressive architecture and design, reviewers were also complimentary of the entertaining information guides provided about the Louisiana governors that occupied the home. Past visitors called the mansion a 'must-see' while in Baton Rouge. Highlights include a curving marble staircase, black-and-white checked marble floors, west wing offices and east wing guest bedrooms. You'll see more similarities between the two structures during a tour of the interior. Indeed, the mansion does have a similar look in part thanks to four large, 30-foot Corinthian columns that support an intricately carved pediment. Though the historical record is disputed, some believe that Governor Huey Long wanted the residence built to resemble the White House so that when he became president he would be familiar with the White House (unfortunately, the governor's mansion was the closest Long got to the White House). Between 19, this Georgian mansion served as the official residence to nine Louisiana governors and their families.
