Day 78 of a Year Long Road Trip Along America’s Scenic Byways

Castillo San Marcos National Monument

We began our morning in St. Augustine, Florida. After my visit to the oldest house and school in Florida, I stopped by the Castillo San Marcos National Monument.  This fort, built by the Spanish, was never defeated in war, but changed hands by treaty.  The fort built of coquina walls, between 1672 and 1695, replaced wooden structures used to protect St. Augustine against the French in 1565.  In 1702 and again in 1740, the fort successfully survived a siege by the British.
