The parents of Daniel and Martha (Barrow) Turnbull achieved high social status in West Feliciana through their immense cotton operations, and Daniel Turnbull himself was known before the Civil War as one of the richest men in the nation. The land that became Rosedown Plantation was assembled not by the then-usual method of Spanish Land Grants but in a group of seven purchases made by Daniel Turnbull from the 1820s through the 1840s. At its largest, Rosedown Plantation comprised approximately 3,455 acres, the majority of which was planted in cotton.
Currently, the main house, historic gardens, 13 historic buildings, and 371 remaining acres of Rosedown Plantation are preserved as a state historic site by the Office of State Parks. State Parks staff and volunteers work to conserve and maintain the site, conducting tours and programs to illustrate plantation life in the 1800s.
In 2005, Rosedown Plantation was placed on the National Listing of Historic Landmarks.
