Always fascinating in forts that were substantially upgraded over their service life (which describes most of America's seacoast defenses) is the manner by which the new was connected to the old. In many cases this made for abrupt, weird connections of new concrete bunkers with the old, lovely brick or granite walls. Fortunately, none of Fort Wool was ever particularly attractive, so the besmirchment seems slight. Hiding behind the aforementioned unchecked weed we see a Second World War-era concrete spotting bunker for Endicott Period Battery Hindman, which mounted two 3" guns.
