Llanelltyd – Cymer Castle


The earliest mention of the Welsh castle Cymer dates from 1116. It was to be erected by Uchdryd ab Edwin and destroyed in the same year. This is the oldest reference to the castle of native Welsh people, which can be identified today.


The castle was built of wood on a semi-circular, earth mound about 13 meters in diameter and today’s height reaching up to 4.5 meters. There are no traces of the moat or defensive ditch. On the hill there are ruins of a building with dimensions of 6.7 to 7.5 meters with walls about 1 meter thick, above a basement with massive foundations. Above it, the building had at least two more storeys. In the south – west corner there was a fireplace and on the opposite side there was a staircase. The building is described as a warning tower from the 16th century or a hunting lodge of abbots from Cymer.

Current state

The castle has not survived to the present day, only the mound and relics of the later 16th-century building in the form of two walls are visible. Entrance to the castle area is free.
