Beginnings of the church of St. Celynnin in Llangelynnin dates back to the twelfth or thirteenth century, when probably today’s nave was created. In the fourteenth and fifteenth centuries, the temple was gradually expanded, first the chancel, and then the northern transept called Capel Meibion, or the chapel of men. It was created so that men could participate in mass in a place separated from women, or because of the desire to separate alien visitors or sick people. In the sixteenth century, the southern transept was also added, however, it was demolished in the 19th century. The church underwent a thorough renovation in 1932 and 1987.
Originally the church consisted of a single, aisleless nave on a rectangular plan. Probably in the fourteenth century, the chancel was added, but it does not protrude from the outer block of the church and is covered by a common gable roof with the nave. In the fifteenth century, the northern transept or the chapel was added, and a century later, no longer existing, the southern transept. In the fifteenth century, a porch was built at the south – west entrance to the nave with an unusual opening in the wall for viewing (squint window). Only the window on the eastern side has preserved the medieval form from the fifteenth century.
