Bryn Eglwys is located some 2km south-east of Abergynolwyn, at what is now a slate quarry known as Bryn-Eglwys quarry. The burial ground is said to have been associated with St Cadfan, and to have formerly been enclosed by a circular wall. Stones are noted to have been moved during the sinking of a shaft 40m to the west.
