Hi Danny, your photos have intrigued me about this site, and I have found a nice self-catering cottage in Feizor that would do me nicely for a week. But it unlikely to happen until next Spring due to other commitments. Meanwhile I remain foxed by the Celtic Wall and why it was built. I thought that it might have been a pointer towards some important site, but when I extrapolated the line of the wall to the north-west, it did not take me to the top of Ingleborough, or even to Gaping Ghyll, so I have ruled that out.
As for the enclosure, the walls look remarkably thick, even if they have collapsed in on themselves.
But it is difficult to gauge the thickness without being on site. What thickness do you make them if we use your ranging stick as a guide? If they were just loose stones, then I would not be surprised if they were as thick as the Celtic Wall?
The enclosure looks like a complete circle, but presumably there is a gap somewhere on the perimeter where the entrance was. Do you remember seeing any gap in the preimeter? If so can you remember which direction the entrance was facing?
Sorry about all of these questions. I hope to get the answers next spring on site.
All the best,
