There are a few things that intrigue me about this particular field:

a) It`s round

b) It`s on a slope, but...

c) The centre is higher than any part of the boundary

d) Most of the other fields in the area have dry-stone walls, this one hasn`t

Unfortunately, I didn`t notice any of this until I looked down on it from two miles away and as I live 100 miles away, it`s unlikely that I`ll be re-visiting Tyfos in the near future.

I`ve no idea as to what it could possibly have been. Has anyone else?
