The Castillo was built with coquina which is a mixture of broken shells and sand. This mixture is bound by calcium carbonate and becomes a compressible material.
This compressibility has allowed the Castillo to absorb the impact of cannonballs instead of having the walls shatter.
One thing to know is Castillo de San Marcos NM is located in the heart of St. Augustine, Florida. The park can be incredibly busy!!!
Parking can be a total pain and you may end up needed to walk a while to get from a parking spot back to the park.
Be prepared for Florida weather, sunshine, and make sure you have shoes on that are comfortable.
