St Thomas the Apostle church was located on the east side of the A4063, set back from the road, in the village of Coytrahen.
It appears to have been built in about 1934 when a grant was approved for the construction of a new church in the village. A Mission Church already existed close to the new site since at least 1899 (NPRN 420676). The church was still present in the 1970s but has since been converted to domestic accommodation ('Ger y Coed'). No further information.
