Found some stuff on that church too. Seems that there is a 12th century church of the same name. The one we saw was built 1839 late Georgian style.

The artist that lives there is a sculptor who is greatly influenced by the archaeology of the surrounding area and he uses Bronze age methods for his work.

If you missed the caerhun duo and rhiw burial chamber then youve probably only seen half of what there is. What you need is a postman, unfortunately I've only got two more day out options before I have to go in hospital (ive not made any plans beyond that yet) just thursday and sunday next week, so I'll probably be heading snowdonia way.
Of course the weather might intervene in some way.
