Dyffryn Burial Chambers
Dyffryn Ardudwy, only four miles from Gwynfryn Farm, has an extraordinary history and is lucky enough to to have four neolithic burial chambers or Portal Dolmens. The first, known as 'Coetan Arthur' dates to around 3500BC, contains two dissimilar burial chambers originally covered by a cairn. Like many similar structures in Wales and Ireland the openings of both chambers face east, remains of a later cremation burial have been detected in the eastern chamber. These tombs are thought to be the earliest in Wales, possibly the British isles, and have contributed much to the dating of other Portal Dolmens in England, Wales, Scotland and Ireland.
You can find the Dyffryn Burial Chambers at the south end of Dyffryn Ardudwy village, signposted on left just before the school. Site is up short footpath with kissing gates, just a few hundred yards from the main coast road.

Bron-y-Foel Isaf Burial Chamber
