Did you know that Florida’s oldest residential neighborhood isn’t just the oldest in the state, but considered the oldest continuously occupied European-established settlement in all of the U.S.?
Over in St. Augustine, Old City South is a historic district lined with ancient oak trees and 18th-century architecture that feels like stepping back in time. It features the highest number of colonial-era homes in the city, from the González-Alvarez House (“The Oldest House” in Florida) to the Miguel O’Reilly House on Aviles Street, which is recognized as America’s oldest public street.

History of St. Augustine and Old City South
Founded in September 1565 by Spanish explorer Pedro Menéndez de Avilés, St. Augustine predates both Jamestown (1607) and Plymouth (1620) by decades.
While the city’s early days were marked by pirate attacks and subsequent rebuilds, the footprint of Old City South has been lived in continuously since those Spanish colonial times. Following a devastating blaze in 1702, which destroyed many of its original wooden structures, the neighborhood began taking its current shape when residents built homes out of coquina, a nearly indestructible sedimentary rock made of compressed shells.
