[1] The village has a long-standing religious association, with an early Christian church having been built there possibly as long ago as the 8th century CE.

The current church of St Crallo was built in the 13th century, and is a Grade I listed building, very large in size for the village it serves.

[3] John Wesley is said to have included the church in his preaching tour of 1771, and the churchyard also contains the grave of the lexicographer Thomas Richards (1710–1790), perpetual curate of Llangrallo, who published the first full-length English-Welsh dictionary in 1753 and dedicated it to Frederick, Prince of Wales.

[9] A manuscript owned by "Thomas Hopkin of Coychurch" was used by the antiquary Iolo Morganwg to provide "genealogies" of the British saints and a pedigree of Taliesin.

[12] The crematorium, which serves the Bridgend area, was built in 1970 and was the last design of modernist architect Maxwell Fry, with stained-glass windows produced by Swansea School of Art.
