Llangernyw Yew

David Bellamy used the same methods as he did when establishing the age of the Tisbury Yew in Wiltshire, including radiocarbon dating.

[6][7][8] In the mid-1990s the church oil tank stood in the space between the two trunk fragments; however, this was moved when it was realised that the tree was ancient.

When this tank was built a lot of the dead wood was removed from the site which makes dating the age of the tree more difficult for dendrochronologists.

According to local tradition, the church of Llangernyw is inhabited by an ancient spirit known as Angelystor (the "Recording Angel" or "Evangelist" in Welsh[9]).

Folklore tells of a disbelieving local man, Siôn Ap Rhobert, who challenged the existence of the spirit one Halloween night only to hear his own name called out, followed by his death within the year.
