After the Castillo de san Marcos’ first siege by the British in 1702, construction began to strengthen the the fortress. Interior rooms were enlarged and ceilings were arched to bombproof the rooms and provide overhead support for the cannons. The vaulted ceilings enabled heavy garrison guns to be placed all around the perimeter of the gun-deck. The enhancements also caused the walls of the Castillo de san Marcos to be heightened from 26 to 33 feet making the fortress even more commanding.
