Saint Augustine, Florida, founded in 1565, is the oldest continuously occupied European settlement in what is now the United States.
America's Oldest City Has Been Inhabited for 460 Years
When Americans think of the nation's founding, Jamestown and Plymouth Rock typically come to mind. But tucked away on Florida's Atlantic coast sits a city that predates both by decades—Saint Augustine, founded on September 8, 1565.
That's 42 years before the first permanent English settlement at Jamestown and 55 years before the Pilgrims landed at Plymouth Rock.
A Spanish Foothold in the New World
Spanish admiral Pedro Menéndez de Avilés established Saint Augustine as a strategic military outpost. His mission? Drive out the French Huguenots who had built Fort Caroline nearby. Within weeks of landing, Menéndez attacked and destroyed the French settlement, securing Spanish dominance over the region.
The timing of his arrival was no accident. Menéndez spotted land on August 28, 1565—the feast day of Saint Augustine of Hippo—and named the settlement in honor of the occasion.
Survival Against All Odds
What makes Saint Augustine remarkable isn't just its age—it's that it survived. The city endured:
- Repeated attacks by English pirates, including Sir Francis Drake's 1586 raid that burned the town
- A devastating siege by English colonial forces in 1702
- Multiple hurricanes and epidemics
- Transfers between Spanish, British, and American control
The iconic Castillo de San Marcos, built between 1672 and 1695, still stands as the oldest masonry fort in the continental United States. Its coquina walls—made from compressed seashells—proved nearly indestructible, absorbing cannonballs rather than shattering.
Why Don't More People Know This?
American history education tends to focus on the English colonial narrative. The Mayflower, the thirteen colonies, the road to independence—it's a tidy story that starts in Virginia and Massachusetts.
But Spanish Florida tells a different tale. For over 250 years, Saint Augustine was a Spanish city. It only became part of the United States in 1821 when Spain ceded Florida to America.
Today, the city embraces its heritage. The colonial quarter features reconstructed Spanish buildings, and the narrow streets still follow the original 16th-century grid. Walking through Saint Augustine feels less like touring a museum and more like stepping into a living piece of history.
The "Oldest" Debate
Some historians quibble about the "oldest" designation. San Juan, Puerto Rico (founded 1521) is older, but Puerto Rico isn't a state. Mexico City predates both but isn't in the U.S. at all.
The key qualifier is continuously occupied. Earlier attempts at settlement—like the Spanish colony at Pensacola in 1559—were abandoned. Saint Augustine persisted, through wars, regime changes, and centuries of transformation, never once becoming a ghost town.
That unbroken thread of human habitation, stretching back 460 years, makes Saint Augustine genuinely unique in American history.
