one of the stone crosses at St Seiriol's Church, Penmon. Churchyard The churchyard contains six Commonwealth war graves: in the east part of the ground are buried two British Army soldiers of World War I and north-north-west of the church are buried three soldiers and an airman of World War II. Assessment The church has national recognition and statutory protection from alteration as it has been designated as a Grade II* listed building – the second-highest (of three) grade of listing, designating "particularly important buildings of more than special interest". It was given this status on 30 January 1968, and has been listed because it is a medieval church that, unusually for Anglesey, dates substantially from the 12th and 13th centuries. Cadw (the Welsh Assembly Government body responsible for the built heritage of Wales and the inclusion of Welsh buildings on the statutory lists) also notes the "fine 16th-century rebuilding of the chancel" and the chancel window. The chancel arch has been described (in a 2009 guide to the buildings of north-west Wales) as the best such arch in the region, and the "fine" east window as "almost too big to fit" in the wall. The 19th-century antiquarian Angharad Llwyd described the church as "a spacious structure, exhibiting some excellent architectural details, and decorated with an east window, of good design, enriched with tracery." Writing in 1846 (before Kennedy's restoration work in 1852), the clergyman and antiquarian Harry Longueville Jones noted a wooden gallery at the west end, above the font, inscribed RICHARDUS DE GREY FECIT 1778. LAUS DEO. He described the chancel arch as displaying "workmanship of good character." The Welsh politician and church historian Sir Stephen Glynne visited the church in 1849. He wrote that it was a "fair specimen of the better sort of Anglesey village church". The nave and chancel were "of good proportions", with the chancel "properly distinguished and developed". He also said that the chancel arch was "of considerable elegance, unusual in North Wales, having excellent moulding and clustered shafts which have a Middle Pointed character."
