A rare and remarkable opportunity to own a private island in the historic, navigable waters of southern Maine. Frank's Fort Island is a secluded, wooded islet located in the Long Reach of the Piscataqua River, just above Eliot Neck and minutes from the Eliot Boat Basin and Dead Duck Boat Ramp. Surrounded by salt marsh, wildlife, and sweeping river views, the island offers unmatched privacy and serenity--while still within easy boating distance to Kittery, Portsmouth, and the open Atlantic.What sets this property apart is not only its natural beauty, but its deep historic significance. In December 1774, local patriots stole gunpowder from Fort William and Mary (now Fort Constitution) in one of the first organized acts of defiance against British rule. That powder was secretly hidden on this island before being used months later in the Battle of Bunker Hill. Few private properties in New England can claim such a direct connection to the American Revolution.Today, Frank's Fort Island presents a one-of-a-kind opportunity for those seeking to create something truly special. While currently undeveloped, the island holds potential for a seasonal retreat, artist's studio, eco-cabin, or minimalist getaway. Buyers are encouraged to consult with engineers and local officials to explore possibilities for a dock, mooring, or off-grid structure. Development will require thoughtful planning and stewardship, but the potential reward--a private, historically rich escape in coastal Maine--is extraordinary.Whether you're a history enthusiast, a nature lover, or a visionary investor, Frank's Fort Island invites you to leave your mark on a storied landscape. Small islands with this level of historical provenance, privacy, legal access, and prime location along the Piscataqua River are exceptionally rare. This is more than a property. It's a legacy.
