Eglwys Crist (Christ Church)

Fine largely unaltered Decorated-style mid-C19 interior. High nave and aisle roofs are arch-braced in 5 bays on carved stone corbels with vertical struts linking the curved braces and collars; exposed rafters carried down as vertical studs below wall-plate to parallel rails beneath. Pointed hollow-chamfered aisle arcades also in 5 bays supported on alternating circular and octagonal columns with moulded plinths and capitals and carved responds at east end. Tall chancel arch similar to nave arcades but without columns or responds astride 3 steps up from nave with brass rail to top (altar has recently been moved back to east wall of chancel where it is again flanked by slate texts); chancel roof arch-braced in 3 bays with cusping to principal rafters which rest on stone corbels of angels playing musical instruments; pointed doorway to vestry on north and wide 4-centred arch to former organ chamber on south, now made into side chapel. Original fittings in nave include complete set of Victorian pews, wooden pulpit, octagonal font with trefoiled panels, clustered shafts to base and elaborate font cover and brass lectern. 3 steps from chancel up to sanctuary which has C19 stained glass in east window. Modern screen across western bay of nave has Sunday School/kitchen beyond; modern screen also between chancel and former organ chamber, which now contains altar and altar rail from the disused St Mary's Church, Dinorwic. The small octagonal font on shaft pedestal now in the south aisle also comes from St Mary's.

Monuments: Gothic monument on north wall of chancel to Henry Grey Edwards, 'first incumbent of this parish', 1856-73; on north wall of north aisle is a small Gothic tablet to 12 people from Dinorwic who died when the pleasure boat they were in sunk off Pwllheli on 1 July 1899; also commemorated by small brass plate at east end of aisle.
