Interior
Very fine and unaltered high Victorian interior, also retaining several notable features (mostly monuments) from the previous church. Nave has arch-braced roof in 5 bays with carved stone corbels, exposed rafters and ashlar pieces, 2 western bays forming an organ loft with pipe organ dated 1863, supported on triple-arched open stone screen with clustered shafts and cusped detailing to the arches and spandrels; balustrade has intersecting and cusped oval patterns. Area to west of screen forms baptistery with octagonal font on clustered shafts (old, probably early C18, octagonal font on short pedestal without base is in tower porch); main body of nave has collegiate-style stalls to walls with high canopied and panelled backs, partly obscuring the stained glass windows, with in front of the stalls a single set of pews, also inward facing; original oil light fittings (now converted to electricity) hang from roof. Similar seating in transepts, north of which has Victorian octagonal stone pulpit with traceried panels and tapered shaft, the south housing the lectern and an old wooden pulpit incorporating a fine early C16 panel, probably of Flemish origin, depicting the Crucifixion; stained glass in north transept to members of Griffith family (dedication date 1846) and in south to Frances Wynn (dedication date 1920 though plaque below refers to a window of 1863). Vaulted crossing with pointed arch on foliated corbels to west and full-height pointed chancel arch to east has 4 carved angels to springing. Reading desks flank steps to chancel, which is entered through gabled and trefoiled arch-way in centre of very fine and highly decorated low wrought-iron screen reminiscent of the work of Francis Skidmore of Coventry, the eastern side with built-in stalls which have free-standing fronts. Hollow-chamfered pointed doorway in north wall leads to vestry; ornate rails to marble-columned high altar and stained glass in east window commemorates Frances Maria, wife of the 3rd Lord Newborough (dated 1857 with initials SBW, London). Timber screen to south of chancel with traceried open panels, partly made up from an old screen, leads to Glynllifon Chapel, which in addition to its monuments (see below) contains several C18 Gothic-style chairs; stained glass in south window depicts Faith, Hope, Fortitude, Justice and Charity.
Monuments:Glynllifon Chapel has on west wall a large marble monument to Sir Thomas Wynn (d.1749)- bust supported on scrolled brackets with shell, cherub below inscription panel; on south wall Ellen and Frances Glyn (d.1711 & 1709)- marble monument with rounded pediment and 2 burning lamps. On south wall at west end of nave a marble wall monument (top broken) to members of the Bodvell family of Bodfan (1731-60) - mourning female figure contemplating an empty urn flanked by fluted Ionic pilasters. Simple C19 brass plate to members of Wynn family on north wall of chancel above door to vestry.
