William Hargrove brought many new discoveries to the attention of the public through published articles in his newspaper the "Herald" and the "Courant" and published a series of guides with references to casual finds.

(The fortress wall was probably reconstructed during his stay and at the east angle it is possible to see this work standing almost to full height.)
