Could be, but to my eyes the usual staddle stone base tapers (like chatsworth) and they taper for a reason (to make an acute angle with the mushroom tops that vermin struggle to climb past) and the others are straight sided and fat and look easily climbed by rodents.

Yeh i agree its probably nothing nl, ba or ia but im surprised no one has come across them before, or at least this one and made a note somewhere, as its not exactly remote?

So it does show you that things can easily be overlooked, doesn't it?

Anyway thanks guys for the input, its probably IS some sort of ruined stilted building tho and like I said I'll take a closer look when I'm next up that way, as i'm into most historical things (Saxon, Norman etc).
