The building is reported to be inspired by the White House in Washington D.C. as it was originally designed by Thomas Jefferson.

[2] When Huey P. Long took office in 1928, the existing governor's mansion was to him a symbol of the past and more importantly the political opposition.

In February 1929, Long succeeded in tearing down the Knox mansion, enlisting the aid of local convicted criminals to disassemble it.

Building the Old Governor's Mansion cost almost $150,000, plus an additional $22,000 for the finest damask and velvet drapes, crystal chandeliers, and other fine appointments.

[1][3][4] It was also added as a contributing resource to the Beauregard Town Historic District at the time of its creation on October 14, 1980.
