13. Fort Necessity (Pennsylvania)
Fort Necessity was quickly constructed by a young George Washington and his men in 1754 as tensions with the French erupted into open conflict. This simple circular palisade became the stage for the opening battle of the French and Indian War, marking a turning point in global history. Though Washington’s defense ended in surrender, Fort Necessity’s story is inseparable from his formative military experiences and the wider clash of empires shaping the future United States.
