Description
The Church of St Michael is a predominantly late 19th-century Gothic revival church. It comprises a three-bay nave with a lower, single-bay chancel, and a north-west porch. The church is built of rubble masonry with freestone dressings. The nave features stepped angle buttresses. The roof is slate with stone copings, cross gable finials, and a single west bellcote surmounted by a cross finial.
The outer porch doorway is a pointed arch above a tablet bearing the date 1888. The reset 14th-century inner doorway is a pointed arch with broach stop chamfered jambs. The nave has single trefoil-headed lights. The west wall has a narrow rectangular light to the left of which is an inscribed stone bearing the date and initials: WW WT 1811. The east window is a late 19th-century ogee-headed light with cusped tracery, with medieval heads as terminals to the hoodmould. The north wall of the chancel has a reset window of a single cinquefoil light with sunk spandrels, and the south wall has a single trefoil-headed light, both repaired and appearing to be late medieval in date.
Both nave and chancel have a late 19th-century exposed roof with arch braced collared trusses with angled braces, down to wall posts on shaped corbels; those in the chancel each have a single number set in a floriate boss which together read 1888.
Set into the south wall of the nave is a 13th-century grit slab gravestone with an incised cross and double head. In the north wall of the nave are two weathered gritstone fragments, probably late medieval; one is the lower part of an incised cross stem on a base of three steps, and the other has a ring at the head and base, alongside a small cross and two rings in the centre. Also set into the north wall is a medieval water stoup - a plain semi-octagonal gritstone bowl.
The chancel has a shallow pointed arch rising from shaped corbels as a springing course. The chancel is raised by a single step, with the sanctuary raised a further two steps. The sanctuary has a mosaic tiled floor and a moulded rail on shaped stanchions with floriate brackets. The east window depicts St Michael and is flanked by marble memorials: one to the right to John Lewis, Rector of Llandegfan, who died in 1743, and one to the left to Elizabeth, widow of John Lewis, who died in 1785.
At the west end of the nave are two further memorial tablets: one to William Thomas, who died in 1772, and one to Morys ap Rhisart Morys of Pentrerianell, who died in 1763.
The medieval font is an octagonal gritstone bowl, recut and probably slightly reshaped.
