The current church building was erected in the 1850s on the foundations of an older church. The architect was Mr. Withers of London. There is a font, said to be of pre-Norman origin, outside, by the front porch, indicating an earlier history of worship in the community.
The churchyard shows the maritime roots of Aberporth, with many memorials to sailors and those lost at sea. A survey of the graves was undertaken some years ago and may be of interest to those doing genealogical research.
Saint Cynwyl was the son of Dunawd. Dunawd and his three sons are said to have founded the Monastery of Bangor-is-Coed, Flintshire. Saint Cynwyl is mentioned in the ancient Welsh tale of Culhwch ac Olwen as "the third man that escaped from the Battle of Camlan, and he was the last who parted from Arthur, on Hengroen, his horse." The Battle of Camlan was in 537.
