St Mary's Church

Gothic Revival style church constructed of roughly dressed stone laid in regular courses from a slightly projecting base. Slate roof. Nave with clerestory, lower apsidal chancel, north and south aisles. Porch to the south surmounted by crucifix with quatrefoil window to side. Bellcote above chancel arch surmounted by metal cruxifix. West end has three single light lancets with trefoil heads. Large circular window above. Windows to aisles are paired lancets with trefoiled heads. Clerestory windows of circular design with cusps. 2-light windows to apse placed high above a band of ashlar.

Plain interior of five bays. The church is principally of interest for the survival of high quality glass in the apse where fragments of stained glass ascribed to the C14 and C16 are now reassembled into the north and south windows. Those to the north depict early C14 monks under trefoiled gables and pointed canopies. To the quatrefoil above is a further figure in a roundel. The south window has figures in roundels under canopies surmounting coats-of-arms. A further figure in a roundel to the quatrefoil above. Mostyn-Lewis suggests a date of c1305 for some of the Treuddyn glass and cites its similarity in style to the glass at Merton College, Oxford.
