I believe the current building dates to the 1870’s. The previous house was burned, along with neighboring Runnymede Plantation, and Middleton by federal troops as they past the Charleston ‘Plantation Row’. Drayton Hall, 5 miles up the row (Ashley River) was ignored due to Yellow Fever being active in the house (or someone smart enough to fly the yellow warning flags out front).
A thought; hardly any plantations look like what we have been shown in the movies for years. The old Hampton Plantation (Santee Delta, SC) comes close. Forest Gump was filmed in several local plantations that come close.
Truth is most plantations either had no buildings being just big rice/cotton fields, or the homes were made of clay bricks. Termites and fires destroyed many homes. Only the wood from Black Cypress was as strong as clay bricks.
