The present building comprises the W end of the double-naved church, medieval with Decorated and Perpendicular tracery; with S porch and remains of the central arcade extending to the E. Walls are of local rubble masonry with sandstone dressings. W wall was partly rebuilt, probably in 1844, now with added buttresses; 2 low buttresses to S aisle and single diagonal stepped buttress at NW corner. Modern slate roof, W gable of S aisle with double bell-cote and stone copings. Main entrance through chamfered basket-headed doorway to S porch, leading to S door of church, of similar design. N wall has pointed arch-headed doorway of 2 chamfered orders to W end, with moulded label and carved human-head stops. Paired window of trefoil headed lights to E end with moulded label. E gables of N and S aisle both with pointed arched Perpendicular tracery windows; S aisle with re-set C15 tracery to upper part, otherwise tracery is modern replacement. The central arcade is of 6 bays with 4-centred arches of 2 hollow-chamfered orders supported on octagonal piers and semi-octagonal responds with chamfered capitals and plain bases; the second pier from W end is embedded in the C19 cross wall.

The double-naved W portion has a C15 roof of 4 bays with exposed arch braced trusses supported on sandstone corbels and renewed purlins and rafters. Masonry walls, once ornamented with texts from the scriptures,:most of these have been lost but part of the two verses from the 84th Psalm, in Welsh is still visible over the N doorway. Most of the internal fittings have been removed and the church now houses fittings from other churches in Gwynedd. Altar is modern, of Cumbrian granite, with moulded top and chamfered angles.
