DisgrifiadGwnnws corn mill is a two storey rubble-stone building, under a (renewed) pitched slated roof. The building probably dates from the late eighteenth or early nineteenth century, although the origins may be earlier. No machinery survives. The discarded cast iron and timber waterwheel from Y Felin, St Dogmaels, (nprn 40259) was installed at Gwnnws Mill in 2002/3 on a new axle and the pond and launder have been repaired. Various complete and bits of mill stones remain around the site.
