History

Late C19 church, built in a Decorated style, to the plans of Douglas and Fordham Architects, of Chester, in 1896, under the patronage of the Tan-y-bwlch estate; the plans are on display inside the church. The original Medieval church was rebuilt in 1814 and the nave of the present building is built on the foundations of the earlier church 'with the addition of chancel, tower and spire': as recorded in the inscription over the S porch. The church is dedicated to St. Twrog and also to St. Mary, giving a connection with the Cisterian monks of the area.
Outside the W end of the church is a sandstone pillar with rounded head and corners c.1.2m tall - known as Maen Twrog and legend has it that Twrog threw the stone down from the top of the Moelwyn, crushing a pagan altar in the valley. Also features in the 4th branch of the Mabinogi, where 'Maen Tyriawg, above Y Felenrhyd', was the burial place of Pryderi, slain by Gwydion.
