Overview

Opportunity awaits at Battery Marshall, located at 3019 Ion Avenue on Sullivan's Island, an expansive and truly one-of-a-kind property offering a rare chance to create something extraordinary.Spanning 1.8 acres, across three contiguous lots, this remarkable site combines centuries of Lowcountry history with a once-in-a-lifetime opportunity to reimagine the future, to build upon this historic setting with creativity and vision.At the heart of the property stands a piece of living history, the Battery Marshall bunker, a resilient concrete structure built between 1930 and 1944 as part of America's coastal defense system.Once housing massive seventy-ton naval guns capable of firing thirty miles out to sea, Battery Marshall played a vital role in protecting Charleston Harbor during World War II. 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.With three buildable lots, the possibilities are endless, from a single private estate with sweeping ocean views, to multiple luxury homes that honor the site's rich history while embracing the best of modern island living. Here, history, creativity, and coastal lifestyle converge, offering something truly rare.Located just steps from the beach, enjoy morning walks on the sand and evening sunsets right outside your door. Golf cart to all the island hotspots including Sullivan's Fish Camp, The Obstinate Daughter, Beard Cats, Mex 1, Poe's Tavern, Home Team, and Dunleavy's Pub. Hop over to the nearby Edgar Allan Poe Library, uniquely housed in Battery Gadsden. Or explore Fort Moultrie, where centuries of history come to life. Enjoy the island's public parks, complete with tennis courts, basketball courts, and playgrounds.Zoned for Sullivan's Island Elementary, Moultrie Middle, and Wando High School. This is Battery Marshall at 3019 Ion Avenue, a legacy property, and a canvas for the extraordinary on Sullivan's Island. Schedule your showing today.
