The Castillo is a masonry star fort made of a stone called "coquina", literally "little shells", made of ancient shells that have bonded together to form a type of stone similar to limestone. Workers were brought in from Havana, Cuba, to construct the fort. The coquina was quarried from Anastasia Island across the bay from the Castillo, and ferried across to the construction site. Construction lasted twenty-three years, being completed in 1695.
After the siege of 1702, the Castillo underwent a period of reconstruction. Beginning in 1738, under the supervision of Spanish engineer Pedro Ruiz de Olano, the interior of the fort was redesigned and rebuilt. Interior rooms were made deeper, and vaulted ceilings replaced the original wooden ones. The vaulted ceilings allowed for better protection from bombardments and allowed for cannon to be placed along the gun deck, not just at the corner bastions. The new ceilings required the height of the exterior wall to be increased from 26 to 33 feet
