Cell-y-Dewiniaid
'The Grove of the Magicians'
A grove of oak trees, long since felled, near Dinas Emrys.
Within this grove, Vortigern's counsellors were said to meet to discuss the events of their times. They were buried in an adjoining field with each grave, at one time, marked by a stone. These, too, have long since vanished.
- Cell, in Welsh, means grove.
