The church in Llandawke was built in the 13th century, but it is not known when exactly. It is believed that it was always under the private patronage of the heirs of Laugharne Castle. One of them, Sir Guy de Brian, rebuilt the church in the fourteenth century.
The church was built of local red sandstone and limestone and the roofs were made of slate. It consists of a four-span nave, a three-span chancel, which is lower and narrower, and a western tower. The tower was built in two stages, its upper part can be from the 17th century. It narrows up to height, with large ogival windows on the western and southern sides. On the north side there is an annex with a spiral staircase.
The entrance to the temple is located on the south side by the ogive portal. On its left there is a double, rectangular window in the style of perpendicular gothic, and on the right side there is a pointed arch window in the style of decorated gothic with an early modern tracery. The gothic window is also located in the south and east wall of the chancel and on the north side of the nave and presbytery.
Inside the chancel there is a piscina and a niche in which there was a tombstone. On the north side is the 14th-century tombstone of Margaret Marlos, the niece of Sir Guy de Brian of Laugharne, unfortunately cut in three by thieves. In the church there is also a stone slab from the 5th or 6th century with Latin and ogham inscriptions.
