The parish church of St David in Llanwrtyd was built in the fourteenth or fifteenth century, and then was rebuilt or renovated in the sixteenth century. The changes affected mainly the windows and the chancel. In the years 1740-1742, the vicar at the temple was William Williams Pantycelyn, the famous Welsh author of hymns, writer and poet. In the 19th century, the building underwent a Victorian renovation.
The church consists of a longitudinal nave, which is the oldest part of the building, and a short chancel from the 16th century, ended with a straight wall. From the south side, the porch adjoins the nave, erected in the 19th century. Probably it was made of older demolition material. Most of the windows come from the sixteenth century, although they were renovated in the nineteenth century.
