Llanpumsaint is situated in the county of Carmarthenshire, South West Wales. The village sits 4.5 miles north of the town of Carmarthen at the confluence of the Aeron and the Gwili Rivers.
The church is interestingly dedicated to five saints: Gwyn, Gwynno, Gwynoro, Ceitho and Celynin, who were brothers. As legend goes, they were charmed by an enchanter, who sent them to sleep and hid them in a cave at Pumsaint, near Caeo.
It said that they will awake when a devout bishop comes to Llanpumsaint. The exact age of the church is unknown, but the building was restored in 1882. The Victorian influence on the church is clearly evident: the windows are almost Gothic, whilst other details have been kept simple. In 1933, the nave and porch were extended.
