The present church of St Thomas the Apostle is a modern construction, having been built within St Dogmaels Abbey precincts (NPRN 94164) in 1847 using materials from the ruined buildings. Within the church is the Sagranus Stone, inscribed in both Latin and Ogham and dating from the fifth century, which helped provide the key to deciphering the Ogham alphabet.
