Capel Jerusalem and attached outbuildings

The building comprises a chapel dating to 1827, along with attached outbuildings. Constructed from squared rock-faced grey limestone with a slate, close-eaved roof, the chapel's lateral facade features six arched openings, each with stone voussoirs. Two long centre windows are present, with a door on each side, each having a blank fanlight and a 20th-century door. Small gallery lights are positioned at the outer ends, their heads aligned with the main windows. An ogee-headed plaque with a half-sphere finial is situated between the centre windows; it reads: "This chapel was rebuilt AD 1827 by the contribution of the church of CHRIST assembled at this place and also the benevolence of the Neighbourhood of Gwynfe in general. David Jones Pastor." The windows contain late 19th or early 20th century glazing. The gable ends are whitewashed and rendered, with overhanging verges. The rear elevation features two 16-pane sashes above two 12-pane sashes, which are not aligned.

A low, two-storey whitewashed outbuilding is attached to the left end, featuring a stone end stack and a nine-pane small sash above a door. A derelict single-storey outbuilding is located behind. The right-end outbuilding, also whitewashed, is longer, with a square 12-pane small sash in the centre and two 20th-century small ground-floor windows. An end wall features a ground-floor door to the left with stone voussoirs, a plank door, and strap hinges. A loft door with a timber lintel is situated above, to the right. The rear of this outbuilding features two windows with stone voussoirs.

Inside the chapel, an exceptional three-sided painted timber gallery rests on four posts: three iron and one wooden. The gallery is characterized by a deep, plain cornice under vertical panels with trefoil heads, the cusps oddly extended with tear-drop forms, and a simple moulded top rail. The chapel houses raked gallery pews and painted, grained panelled box pews arranged in four blocks, with some inward-facing pews at the front of the side blocks. There's also a plain panelled 'set fawr'. The pulpit, dating to the later 19th century, has steps up each side, a canted front with arch-headed panels, and turned half shafts. The ceiling was altered in the 20th century, featuring a plain border surrounding 15 recessed panels of painted plaster. The central panel displays an oval painted world map inscribed ‘Ewch i'r holl fyd a phregethwch yr efengyl i bob creadur’. 20th-century lobby doors provide access, and stone steps lead up to the gallery. A plaque commemorates David Griffiths of Glanmeilwch (1792-1863), who served as a missionary in Madagascar for one and a half years.
