St. Augustine Ghost Tours: A Complete Guide to the Nation's Most Haunted CitySt. Augustine has earned its reputation as one of the most haunted cities in America - and with more than 450 years of recorded history, it's easy to understand why. From Spanish colonists and British soldiers to yellow fever victims and Civil War prisoners, the layers of human experience that have unfolded within these ancient walls have left behind more than just historical records. Many believe they've left behind restless spirits as well.Why St. Augustine Is So HauntedFounded in 1565, St. Augustine predates the founding of the United States by more than two centuries. The city has witnessed conquest, disease, warfare, slavery, and countless personal tragedies.
