I mentioned the word "code" in the context of those, like you that refer to it as such.
AS the British National Trust curators and caretakers of the Shugborough Estate have stated on their official site, that get a minimum of three "solves" a week, and with all the thousands of "solves" presented, none are the same.
Do you understand that the Shepard's Monument on the Shugborough Estate was constructed as a folly, a garden ornament decoration fantasy piece along with several folly structures by Thomas Anson for the estates grounds, and most importantly, NOT a monument commemorating anything.
If you have questions concerning the Shepard's folly, or want to share Franklin and your "solve", Email the curator at the Shugborough Estate and discuss your findings.
