The present church dates from the early thirteenth century.
One of its great benefactors was Hywel ap Meredydd ap Cynan, the Lord of Ardudwy, the commot which has given its name to the Rural Deanery of Ardudwy in which the Parish of Llanaber is situated.
Hywel was a great grandson of Owain Gwynedd and a near relative of Llewelyn the Great.

The plan of the church consists of a nave, with north and south aisles, and a long narrow chancel.
Entering the church by the south porch, rebuilt in the nineteenth century, is the south doorway, a still-standing example of Early English architecture.
This doorway, built of yellow sandstone, is deeply recessed and is composed of six shafts on either side.
 The north door opposite is much narrower and of simple design.

The nave is divided on either side into five arcades.
They show the transition from Norman architecture to the Early English Style.
The piers are Norman in character with foliated capitals from which spring pointed arches.
The four clerestory windows on either side of the nave are examples of Early English lancets, whilst the two long lancets of the west wall are part of the nineteenth-century restoration.

The chancel, which is separated from the nave by an Early English arch, is approached by a flight of steps, necessitated by the sloping nature of the site on which the church is built.
The east window is an example of a single Early English lancet with very wide splays and shafts in the inner arch.

The main roof timbers, both in the Nave and Chancel, date from the sixteenth century, whilst the ceiling above the sanctuary is panelled and its bosses and carvings picked out in gilt and colour.

The font is octagonal in shape.
The bowl is modern and it stands on a very much older shaft.
