The call of the church at Llanafan Fawr and its nearby cemetery suggest the early mediaeval roots of the temple, but the date of construction is unknown. In the sixteenth century, Thomas Huet was buried at the church. He was the first to translate the book of Revelation into Welsh. In 1765 the tower was rebuilt using the base of the older structure. In 1887, the church was in ruin, and therefore it was decided to drastic reconstruction and rebuilding. The chancel was demolished, which was replaced with a new one, the southern wall was repaired, and a porch has been demolished and new one erected.
The church is orientated towards the sides of the world, a single-nave, aisleless building on a rectangular plan, with no chancel separated from the outer corpus. From the west side has a four-sided tower. There are many stones embedded in the walls of the church with carved decorations dated to the 5th/6th century.
