A settler at Fort Caroline drew this image in 1564: It's thought to be the first print of a European structure to be built in the New World! As you can see, it doesn't really resemble the Fort Caroline that we have today, though the three-pointedness of it is certainly in evidence.

This picture was taken from a sign at the fort, but reproductions of this image were sold at the Fort Caroline's gift shop...were. One framed copy was on display, but they no longer had any for sale, and the Ranger on giftshop duty kept making it worse by saying things like "we used to have it...lemme check in the back, oh, nope, all gone...yeah that's a good one..." Curses.
