In 1565, St. Augustine was founded and became the first continuously-occupied European settlement in what would later become the continental United States. For the past 37 years, archaeologist Dr. Kathy Deagan of the University of Florida has spent her summers excavating the area of the "Fountain of Youth" and learn more about the early Spanish settlement.

Over the years, Deadan has found many Spanish artifacts, mixed with those of Native Americans, proving her theory that settlement founder Pedro Menendez de Aviles used some Native American structures before being driven out by the local tribes. Documents report that the Spanish were driven off by fire, evidence of which has been found at the site.
