The largest pre-Civil War mansion in all of the American South burned to the ground as a devastating fire ripped through the historic wooden structure built nearly 200 years ago.

The historic Nottoway Resort, Louisiana's largest antebellum mansion, was destroyed by fire Thursday. Ten fire departments fought the blaze at the 166-year-old landmark.

The Nottaway Plantation in White Castle, Louisiana, started burning around 2am on Thursday morning and was completely destroyed within hours despite the efforts of 40 firefighters. At 53,000 square feet it had been almost as big as the historic core of the White House and was used as an events venue.
