Interior
Nave and chancel separated by simple C12 chancel arch, with chamfered imposts, now plastered over. Nave has late C17 roof of chamfered collared trusses on wall posts sprung from shaped corbels. C14 N doorway (now giving access to vestry), with reset weathered gritstone water stoup alongside, above which is a carved cruxifixion stone, probably C13, bearing a crudely carved figure on a wheel cross with pierced spandrels. The chancel has a C16 roof with closely spaced arch-braced trusses; these now rest on a C19 beam carried on shaped corbels, spanning the wide opening between chancel and N chapel. The chapel is a C16 addition, and its roof is similar to that of the nave though with broader trusses; the N truss has a trefoil above the collar beam.
The church retains some C18 memorials, including: a recessed stone memorial to John Williams of Bodgynda d.1721; to Rowland Jones d.1757, Mary Thomas his wife d.1763; to Owen Thomas of Park d.1783, Margaret his wife d.1794, Owen their son d.1702, Elizabeth their daughter d.1796 and Anne, daughter of Wm. Edward of Llanfaes d.1790. Other C19 and C20 memorials mainly commemorate the Williams family of Parciau, the estate on which the church stands; but there is also one well detailed Art Nouveau style stone memorial to John Groome, 4th Officer of the Royal Charter, which sank off the coast at Moelfre.
The church fittings are C19, and pews, pulpit, reading desk and chancel rail are all embellished with pierced trefoil decoration. Above the chancel rail on the S wall of the chancel there is a wooden panel, formerly part of a pulpit, with conventional leaf ornament and bearing the date and initials: BAB / ANNO / DOMI / 1644.
At the W end of the nave there stands the font; probably C12, a plain tapered bowl with a projecting band at the base. There is also a tall, much weathered water stoup of unknown date.
