It is designated by Cadw as a Grade I listed building,[1] and is under the care of the Friends of Friendless Churches.

Unusually, the church escaped restoration during the Victorian era, and so its interior is still little changed since about 1800.

Describing the reasons for its Grade I listing, Cadw states it is "a rare example of a medieval church unrestored in the 19th century, so retaining an exceptionally complete set of 18th-century furnishings".

Its plan consists of a nave and a chancel under a single roof, a south transept acting as a chapel, and a north porch.

In the southwest corner of the chancel is an oak pulpit and a reading desk over which is a sounding board.

The seating in the nave, chancel and transept consists of box pews and benches, some of which are inscribed with initials and dates.

An early 19th-century brass candelabrum, a chalice dated 1723, and a silver salver of 1752 which were formerly in the church are now in the care of Bangor Cathedral.
