In the late 18th century, the Spanish flag rose above the Mississippi at the site of the Fourth Bluff, a fort that the Spanish called Fort San Fernando de Las Barrancas. Though the Spanish presence may have been short-lived (1795-1797), its existence was the backdrop to a geopolitical opera between an ebbing empire, a nascent nation and fractured Chickasaw Nation politics. And further, it's just one place where the Spanish imprint, however faint, still echoes.
