Llys Euryn

Llys Euryn was one of the local estates in the Dinerth area owned and occupied by Ednyfed Fychan (d. 1246) — full name Ednyfed Fychan ap Cynwrig — who was seneschal to the Kingdom of Gwynedd in northern Wales, serving Llywelyn the Great and his son Dafydd ap Llywelyn.

The present structure is late medieval and may be the house occupied by the Conwy Family until 1629 when it was sold to Sir Peter Mutton.

During the working life (end of the 19th century) of the nearby limestone quarry, a small hut was built against one of the walls which was believed to house the blasting materials.

Much of the vegetation was stripped away, the interior walls and a large fireplace were uncovered, the blasting hut removed and the hole in the chimney filled-in.

Finally, stone chippings were added to prevent further vegetation growth and an informative sign about the sites history was erected.
