Like most people I had an image of plantation houses, they were ‘Gone With The Wind’ mansions.
I have only seen one building that looks close. Most are much more modest, large, but not ornate.
The really old ones, out in the marshlands where rice, indigo, and sea island cotton were grown, were built over long periods of time. Many were replacements (not this one) for buildings that had burned or been destroyed by wars.
Common to most all is a porch, bricks, tall windows for breezes to pass through, and multiple sections added over years. This building dates to 1790.
