Miss. Code Ann. § 39-7-15

Upon majority vote of the board any Mississippi landmark on public or private land may be determined to be of no further historical, archaeological, or architectural significance, or not of sufficient significance to warrant its further classification as such, and upon such determination it may be removed from such designation. In the case of sites located on private land that have theretofore been designated by instrument of record, the board is authorized to cause to be executed and recorded in the deed records of the county where such site is located an instrument setting out such determination and releasing the site from the provisions thereof.
