How interesting. You going to detect the area? Be neat to find items that would maybe be a clue to the age of that wall. Look like no mortar was used in construction of the 3rd picture.
Tamrock , I can't wait to go back and detect , the third picture is actually the remains of the barn , unfortunately a storm was moving in and the rest of my pictures turned out to dark . Both structures are much larger than you can tell in the pictures . I'm not sure of the age yet but for the area it is in it was a very nice place in its heyday . And hopefully the ground is loaded with old silver ! I will post updates of my finds .. Fingers crossed!!
Welcome!
Good luck detecting that spot. The building in the first photo's looks like it is tall enough to be church or was once a business. Normally that much effort and money would not be spent on a regular home.
