What is the St. Augustine fort made of? Coquina, which is actually a rock made out of seashells! Coquina is formed when the tiny clam donax variabilis dies. These are the small pink, lavender, yellow, or white shells you see along the Florida coastline at the waterline. These shells accumulated in layers over centuries, forming a rock. It is found in very few places in the world. Here, from the National Park Service, is the fascinating story of coquina and the construction of the St. Augustine fort.
Where do I park at the St. Augustine fort? A city parking lot is located in front of the Castillo de San Marcos and costs is $2.50 per hour. The pay station accepts credit and debit cards.
What year was the St. Augustine fort built? Construction began in 1672, 107 years after the city’s founding. The core of the current fortress — it was modified over the years — was completed in 1695
