Coquina Rock

The well-preserved fortress is built out of a very special sedimentary rock called Coquina. This is a rare building material because it takes so long to form as a shell stone rock. Furthermore, it's only found in a few coastal regions in the world! Florida and North Carolina are the only places in the U.S. home to the rock. Back in the day, the Spaniards would transport the rock to their building location and wait 6 months to a year just to use it. That's because they needed to leave it out in the sun to dry out before it was usable.
