Castillo de San Marcos
a 17th-century Spanish coquina-stone fort over the bay
Castillo de San Marcos is one of the places Roamward flags on the A1A Scenic & Historic Coastal Byway because it gives the drive its texture: a 17th-century Spanish coquina-stone fort over the bay. Use it as a planned pull-over instead of letting the route become a blur between towns.
How it fits the drive
The A1A Coastal Byway runs Ponte Vedra Beach → Flagler Beach, FL. Florida’s Atlantic coast past the oldest U.S. city.
