Memorial church erected between 1853 and 1855 to the memory of Colonel John Lloyd Salusbury of Galltfaenan Hall by his daughters Mrs Townsend Mainwaring and Mrs Charles Mainwaring. The church was designed by Sir George Gilbert Scott, architect of London and was conceived in his characteristic 'middle-pointed' style of the late C13/early C14. A lavish commission, the arcade columns and capitals were made of polished Mona marble and given a profusion of naturalistic foliate carving by the Denbigh mason Mr J Blinstone. This was undertaken under the direction of the architect who took the mason off to London for instruction and who later professed himself particularly pleased with the result. A vestry was added by Sir Giles Gilbert Scott in 1907 under the patronage of Colonel Charles Salusbury Mainwaring, also of Galltfaenan Hall.


Memorial church in early Decorated style; of uncoursed, dressed limestone blocks on a slightly-battered plinth and with limestone dressings. Steeply-pitched roofs, saddle-backed to aisled nave, of (original) copper-coloured Westmoreland slates; oversailing eaves with kneelered gable parapets and overlapping copings with stone gable crosses. Large gabled, twin-arched bellcote to eastern nave gable, with tall trefoil-headed bell openings and cruciform carving to recessed oculi on both W and E faces; surmounting gable cross. Gabled S porch with pointed-arched outer entrance and moulded label returned onto carved head stops; geometric side lights of two conjoined, cusped triangles with quatrefoil oculus over. Heavily-moulded inner arch with similar label stops and decorative ironwork to boarded doors; two contemporary Gothic iron footscrapers flank the porch entrance. Two-light tracery windows flank the porch, with carved head stops to returned labels; the windows break the eaves and are contained within elegant gables. Tall 2-light W window with tracery head and returned label as before; flanking buttresses define nave and aisles, the latter with tall single lancets to the ends. Three further, similarly-gabled windows to N aisle. Stepped-up S door to chancel with pointed outer and trefoil inner arch; boarded door with decorative ironwork. The entrance has a coped, steeply-gabled canopy, supported on double corbels; contemporary iron foot scraper, as before. Large 3-light E window with Decorated tracery to head and carved label stops as before; stepped buttresses flank, that to L angled. That to the R is straight and marks the division between the chancel and the flush adjoining N chapel. In the valley between the gables is a fine 2-stage chimney with broach-stopped chamfered edges and crenellated capping. 2-light E window to N chapel with paired trefoil-headed light and surmounting quatrefoil oculus within a large, blind, pointed arch with cross carving to its upper section; in the western gable apex a tracery oculus. Stepped buttress as before to NW and NE corner, the latter angled.

Adjoining the N chapel to the N is the single-storey early-C20 vestry; construction as before on a battered plinth and with similar slate roof. Squat chimney with moulded capping to coped N gable. Segmentally-arched boiler entrance to E face at L. To the R, two squat 2-light Tudor-arched leaded windows with cusped lights and depressed ogee to moulded top; continuous label course. On the W side is a stepped-up entrance to the R with moulded, pointed arch and returned label; boarded door with decorative ironwork.


Fine clustered scissor-truss roof to tall nave, on stone-corbelled wall plate. Four-bay arcade with pointed limestone arches and moulded sandstone labels; these with carved head stops. The arcade columns are of polished Mona marble on moulded limestone bases. Naturalistic foliage carving to capitals, each representing different plants or leaves observed from nature.

Early English style font of Llaniestyn red-stone (from the Marquis of Anglesey's quarry) with three different additional types of marble; large basin on a moulded base with 4 columnar supports with naturalistic foliage capitals. The whole is raised up on a tooled limestone plinth of cruciform plan, with steps on all sides; moulded top with fine wrought iron decoration to wooden font cover. Square pulpit of similar style and material with marble stepped access; engaged corner columns, moulded base and top and a central quatrefoil with the Christological monogram. Simple roofs and similar pavements to aisles, with tall tracery windows breaking the eaves. Their gables are supported internally on fine foliated corbels. Returned, moulded label to S entrance inner face, with further carved heads as label stops. Fine contemporary grisaille stained glass to W window, by James Powell and Sons. Commemorative figurative stained glass windows to the aisles, that to the S aisle and two to the N aisle are to Townsend Mainwaring, JP, MP, of Galltfaenan Hall, (d1884) and include heraldic panels.

The chancel has been stripped of its plaster. Inlaid marble floor (in memory of W P Jones of Llannerch, 1955) and similar to stepped-up sanctuary. Two further grisaille windows by Powell and Sons to S side. Large E window with stained glass depicting the Passion and commemorating Col.
