1. Fort Frederica (Georgia)
Nestled on St. Simons Island, Fort Frederica was a strategic British outpost built to defend the southern colonies from Spanish incursions originating in Florida. Though overshadowed by the famous Castillo de San Marcos in St. Augustine, Frederica’s garrison held the southern frontier and played a crucial role in the 1742 Battle of Bloody Marsh. Today, archaeological remains at the site reveal its original layout and offer a tangible link to a time when the fate of Georgia—and all of British America’s south—hung in the balance.
