The church in Llawhaden was founded in the 12th century on the place of a much older temple. It was consecrated to Saint Aidan, an Irish 6th-century monk who was a disciple of Saint David. In the 13th century, a tower was built on the south side of the nave. At the turn of the thirteenth and fourteenth centuries, the building was heavily rebuilt, among others a second tower was erected on the place of the old nave, and a new, larger nave was built on the north side. In the place of the previous northern chapel, a chancel was established. In an unusual way, the old and the new tower were connected with each other by the southern and northern walls. In the nineteenth century, the church underwent two major restaurants: in 1834 and 1862. The roofs were replaced, the structures were reinforced, new stained glass windows were installed, a western porch was erected and a chapel of the Roch family was built on the site of the old chancel, which was later turned into a sacristy.
The church from the fourteenth century consisted of an unusual arrangement in the form of a rectangular nave, a narrower and shorter, rectangular chancel on the eastern side, a set of two connected towers from the south: an older south tower from the thirteenth century and adjacent to its northern part, a newer tower from the 14th century. The western porch and sacristy on the south-eastern side are early modern additions, although the sacristy was erected on the site of the original presbytery from the 13th century. The original entrances to the nave were on the north and south sides. Most of the windows are two-light with finials in the form of a trefolis and with a smaller quatrefoil at the top, they were renovated in the 19th century. Both towers are topped with typical parapets on corbels and battlements. The larger tower has a stone vault in the room in the ground floor, there is no preserved floors in the smaller tower
