Castell Bryn Gwyn ancient settlement on Anglesey

Castell Bryn Gwyn ancient settlement on Anglesey.

Castell Bryn Gwyn SH 464671.

Located just outside Brynsiencyn. Believed to be an ancient religious sanctuary dating from 4500BC. I would guess the diameter of the circle to be a couple of hundred feet (ish). When I visit these sites I often wish that the Gwynedd Archaeological Society would have the funding to uncover this type of site so we may have a better look and therefore understanding of what they might have looked like.
