Glandwr Chapel

The Glandwr Chapel is a building dating from the 18th century, constructed of painted stucco with a half-hipped slate roof. It is a two-storey structure with a four-window long facade. The facade features four arched first-floor windows above two doors, set within rubble stone gabled porches that also have arched entries. Decorative fretwork brackets are positioned under the eaves, punctuated over each window. The windows are of a 'Florentine' design, featuring two lights of tracery with roundels. Two-panel doors with glazed upper panels provide access. The porches are characterised by coped gables, flush buttresses on either side, chamfered plinths and imposts. A pedimented slate memorial is attached to the left end of the facade, commemorating W Lewis (died 1815) and made in 1835 by E Lloyd of Felindre. A plaque to the right end memorializes Rev Lewis Thomas (died 1745), erected in 1842.

The ends of the building are two-storey and feature arched windows, larger on the ground floor. The south end is stuccoed, while the north end and a similar three-window rear elevation are of cement-washed rubble stone. A blocked square-headed window is visible on the rear first floor to the left. Brick heads are present above the arched windows on the north end, and these windows have a central mullion and marginal glazing bars.

The square interior features a three-sided gallery supported by five iron columns with acanthus capitals. The gallery front is timber with painted graining above the columns, followed by a cornice and a valance of fretwork consisting of linked half-circles. The upper rail is adorned with a cast-iron band of small lozenges between bands of half circles, with a similar fretwork band beneath the top handrail. The pews are arranged in three blocks, curved to a concentric plan, with boarded backs, roll-moulded tops, and shaped bench ends. Correspondingly curved raked pews are found in the gallery. A curved set fawr (choir stalls) is also present. The pulpit is accessed by steps on each side with twisted balusters, heavy chamfered newels, and pyramid finials. The pulpit front is arched, composed of a 1-3-1 panel arrangement, with the end panels curved and ringed column shafts with arches above fixed panels. A cornice displaying a rope moulding and a ribbed, panelled ceiling divided into 12 sections with four roundels completes the interior. Several older plaques have been refixed to the side walls; the south wall displays carved arms commemorating John Devonald of Graig (died 1757) and his son John (died 1769), along with an inscription. The north wall has a plaque dedicated to Lazarus Howel of Blaiddbwll (died 1776). Two internal porches replicate the fretwork detail found on the gallery.
