The church in St Ishmael was mentioned for the first time in historical documents in 1115. At that time, it was granted to the abbey in Kidwelly. The granting was confirmed in 1303, and in 1368 the right to appoint parish priest (advowson) in St Ihmael was obtained by the bishop of St Davids. During the Reformation, advowson passed into the English Crown. At the beginning of the sixteenth century, the building was enlarged by a tower, built on the southern porch. According to tradition, it was damaged during the storm and remained reduced later. In the years 1859-1860 the church underwent a thorough renovation, during which windows, roofs and internal equipment were replaced, and the southern transept was turned into a sacristy.
The medieval church consisted of a rectangular, four-span nave and a not externally separated two-span chancel. In the 14th century, the porch and transept were added from the south, and in the fifteenth century, the northern nave. It was erected in the same shape as the main nave and chancel, and was crowned with a separate, gable roof. Transept is connected to the presbytery with a skew passage. The last addition, probably from the sixteenth century, was the tower built on the southern porch.
