Parish Church of St Mary

Long, continuous nave and chancel. Simple arched-braced collar roof consisting of 31 clustered trusses, probably C14 or early C15; flagged floor. Late C19 figurative stained glass to western-most window of N wall; plain bowl font on column, presumably early Medieval. Round-arched niche to L of E window, a fragment of the pre-C15 E wall. c1830 Gothick furnishings with simple pews with moulded rails to flat bench ends. Sunk-panelled octagonal pulpit on moulded base; stall with open Decorated tracery. The S chapel opens out from the chancel, the supporting bressummer for its wide, flat opening being carried on a figurative engaged capital set into the E wall; this is perhaps C13 and is re-set. 2-bay roof with arched-braced collar truss with plain struts; protruding dowels and chamfered decoration. Above the chapel's E window is a long oak board bearing the inscription in raised letters: 'EDWARDVS : WILL: IAMES: AR: ET: / GRACEA: UXOREI: Q HOC: OPVS: FIERI/ FECERVNT: ANNO: DOMINI: 1591.' This refers to Captain Edward Williams of Maes-y-Castell, High Sheriff of Caernarvonshire in 1570. W wall mural tablet with arms cartouche to Hugh Davis of Caerhun, d.1721; E wall monument to Catherine Hester Hemming and family, d.1829. 2-bay vestry (former S porch) with C15 collar-truss roof with windbraces.

Simple church with long, continuous nave and chancel and S chapel addition flush with the E end. Of random rubble construction under a renewed slate roof; the walling includes a quantity of squared red sandstone blocks which are probably re-used Roman material from the site. Rough-kneelered and stone-coped W end gable parapets with large surmounting double-bellcote. This projects slightly beyond the line of the W wall and is carried downwards to rest on 4 rounded corbels; in the centre of this projection is a carved stone crucifix in a shallow cusped, arched niche of C15 type. Depressed-headed bell openings with triangular profiled rubble coping to flat top; central stone gablet. Deeply-recessed W door with gently-pointed arch; C18 studded plank door. 3 post-Reformation 3-light mullioned leaded windows to N side, those to the L and R of re-used sandstone and slate-stone respectively and that to the centre with C19 pale sandstone mullions. Wide, segmentally-arranged sandstone voussoirs appear between the first 2 windows from L, testifying to an earlier opening. Simple C15 3-light mullioned E window with arched sandstone heads. Adjoining to the S and flush with the E end, the S chapel. This has a 2-light mullioned window to its E side with wide, cusped, arched heads and a similar 3-light window to its gabled S face; original ferrementa. Above, an eroded sandstone plaque formerly bearing the initials EW and GW flanking the Williams arms, and with the date 1591. 2 further post-Reformation windows to the nave S wall, that towards the W of 3 lights with slate mullions and that towards the E a wooden 2-light window. Beyond, towards the W end, a C15 rubble S porch, largely rebuilt as a vestry in the C19, though retaining its W wall and roof structure. This now has a small, arched and cusped window to its S face, re-set and probably originally in the porch E wall.
