And you're correct Dave. It's Rhiwddolion near Betws Y Coed, the village was finally abandoned in the 1940's. It had it's own shop and Chapel which also doubled up as the school.
Saw a photo of the shop in the book Dyffryn Conwy and there were four people in the picture including the shop owner. The large lintel on the fireplace had a date of 1687 on it.
