After the war, these fortifications were sold into private ownership, beginning a new chapter of coastal living. Today, Battery Marshall offers the opportunity to reimagine history itself, transforming this storied structure into a modern coastal residence, a private retreat, or a bold architectural centerpiece that bridges past and present.
