That the first line could be referring to Octave Chanute, who was friends with and helped out the Wright brothers. That would start you at kill devil hills. If that is the case I think you'd be going across the Baum bridge the opposite way than you are saying here, right? If you take The Window in "the land near The Window" to mean the Lost Colony Amphitheater, then it could still be the Elizabethan gardens.

ETA: and this line “From this hallowed ground they walked away through the dark forest and into history.” is apparently on a plaque at the entrance of the gardens.
