Church of St Peter

This is a small, rural church in a cruciform plan with transepts offset to the east end. It was built probably in the 15th century, of rubble masonry with large stones used as quoins at the corners of the transepts. Some openings have sandstone dressings. The roof is slate, with a tiled ridge, stone copings, and gable cross finials with splayed arms. A single bellcote of dressed stone sits at the west gable, topped with a cross finial.

The west end of the north wall features a 15th-century doorway with a pointed arch set within a rectangular frame, framed by casement moulded jambs; geometric patterns are carved into the spandrels. Above the doorway is a mid-19th century window with paired round-headed lights in a rectangular frame, similar to the 17th-century north window in the north transept. A corresponding doorway is located in the south wall, probably also 15th-century, with chamfered jambs and now partially filled with a window in the upper part. The east chancel window is a mid-19th century pointed arch window composed of three trefoil lights with cusped tracery and a hoodmould. The east window of the north transept is also mid-19th century, featuring a paired rectangular light that mimics the 17th-century windows in the east and south walls of the south transept.

The roof is exposed, with braced and collared trusses likely dating to the mid-19th century. The fittings are predominantly mid-19th century, although the reading desk incorporates two later 15th-century bench ends with rough tracery. One of these bench ends contains a carved mermaid holding a comb and mirror, originally from the Church of St Elian at Llaneilian. The chancel is raised one step, with the sanctuary a further step, featuring a moulded sanctuary rail on shaped balusters. A pointed arched recess with a moulded surround contains a mosaic of St Peter to the left of the east window; a matching moulded surround is found on the south wall of the chancel.

The octagonal font sits on a stepped plinth in the north transept, near which are several 18th-century gravestones commemorating Griffith and Edward, sons of Richard Prichard (died 1759), and to Richard, his son (died 1762); also to William Griffith, tenant of Glyn (died 1746) and his wife, Jane Roberts (died 1762); and to Robert Roberts, tenant of Glyn, and his wife Catherine (died 1714). Earlier memorials are on the north wall of the nave, including one in stone to William Lloyd, MA Rector of Llaneilian (died 1661), and below it a bronze memorial to Anne Lloyd (died 1763), wife of Robert Morgan, Bishop of Bangor (died 1675), bearing a shield of arms showing a lion rampant reguardant (Gwaethfoed for Morgan) impaled with the arms of Lloyd of Henblas. According to the Royal Commission on Ancient and Historical Monuments Wales (RCAHM), the church also contains a memorial to Robert Warmingham (died 1723). A vestry is located at the west end of the church, and a rough stone piscina is situated to the right of the north doorway.
