Walls half-built, cannons not yet mounted in their final positions, the structure nonetheless had to hold, because the southern bar of Vitoria Bay was the only way in and out of the Captaincy of Espirito Santo, and whoever controlled that channel controlled everything behind it. The fort held, more or less, and the Portuguese kept their colony. The circle of stone that survived that early test was renovated, expanded, and reconfigured over the next three centuries, passing through the hands of the Portuguese Crown, the Imperial Brazilian Navy, and the modern Brazilian Army. Today it anchors the 38th Army Infantry Battalion on the same rock where it stood in 1702.
