Moriah Calvinistic Methodist Chapel

The Moriah Calvinistic Methodist Chapel, built in 1880, is a large, two-story building constructed of snecked, roughly-dressed slatestone with dressings of Penmaenmawr stone. The slate roof features dentilated eaves on the sides. The symmetrical “showpiece” facade is designed in an Italianate classical style. The chapel is tripartite, set on a moulded plinth, with a wide, projecting, and pedimented central entrance bay flanked by narrower bays. Plain pilasters frame the bays, rusticated at the lower stage and quoined at the upper storey, above a plain stringcourse. The central entrance has paired round-arched doorways with pilasters, keystones, and a shared, heavily-moulded entablature. The doorways retain their original and unusual six-panel sliding doors. An inscription above the entrance proclaims: 'Moriah Calvinistic Methodist Chapel AD. 1880'. The upper stage features a group of triple arched windows, with a projecting, moulded pediment over the central window, supported by console brackets. Tall windows are present on both the ground and upper floors of the flanking bays; those on the ground floor have lugged architraves, and those above are arched, all with original three-pane glazing. Pierced decorative balustrades accent the outer bays.

The sides of the building have five bays, with the west side being slate-hung. Recessed sash windows with marginal glazing are present throughout. Ground-floor windows have flat triangular lintels, while those above are arched. The east side exhibits dressed quoins and lintels, with projecting sills.

The interior is galleried with boxed pew seating and polished pitch pine joinery. A U-shaped gallery provides raked seating in six tiers at the rear and three on the sides, arranged in numbered box pews. The gallery front is curved and panelled, featuring moulded details and fluted dividing pilasters forming compartments. Narrow, painted cast iron tracery panels are set below a mahogany rail. A clock face by G. Owen is situated in the centre. The gallery is supported by cast-iron columns with stiff-leafed capitals. The ceiling has a simple plaster cornice and coving, with boarded construction and simple geometric compartmentation defined by moulded wooden ribs. A cast-iron tracery rose sits at the centre, accompanied by four smaller flanking roses. The gallery retains its original oil-cloth runners with key-pattern borders. Access to the gallery is provided by well stairs on both sides, incorporating panelled dados and rails, and six-panelled doors. Ground-floor access is via four-panelled, part-glazed doors. Boxed pews on the ground floor are angled towards the "set fawr," enclosed by panelled mahogany rails with iron tracery detailing, and columnar newel posts with ball finials. The “set fawr” has two tiers with a geometric panelled front, moulded rail, and flanking, sweeping stairs. Twin pilasters flank the recessed seat and support a heavily-moulded, dentilated entablature with an incised foliate frieze, surmounted by a swan-neck pediment crowned with geometric finials.
