Using historical documents and photos, Salt Marsh Galleries has created three cool historical visualizations of Castle Pickney and combined them into one three-minute-long YouTube video. The first segment of the visualization shows the fort on the eve of the Civil War, the second shows the fort when it served as a prisoner of war camp early in the war, and the third shows the fort late in the war. Marsh Galleries works with architects, home designers and builders to visualize their projects before ground is broken to begin them.
