Initially a chapel of ease to Church of St John the Baptist, Llanblethian of Cowbridge as a medieval market town.

The church is thought to have been built as part of the construction of the medieval town in Cowbridge during the late 13th century.

[6] In 1848 a charitable call was made by the church for necessary "re-pewing and re-paving", with a target of £250 requested, much of the money coming from wealthy parishioners.

The tower has a corbelled wall head from which angle broaches slope up to an octagonal battlemented top section.

[4] The interior of the tower houses arches on the east and west sides, both part of the original 13th century design.

[4] There are two hatches in the east wall, assumed for the dispensing of alms, which Newman describes as 'a most unusual feature'.

The south chancel windows depicts Biblical stories of instruction to commemorate one of the headmasters of Cowbridge Grammar School.
