[3] The earliest record is from the Liber Landavensis (12th century) which states that Guidnerth was pardoned three years after killing his brother Merchion and was granted the land and woods from the coastline of Llangadwaladr to St. Cadwaladr's church in a charter witnessed by Bishop Berthguinus sometime around the year 700.

Cadwaladr was the final Welsh King of Britain, dying in AD 664, according to Geoffrey of Monmouth.

[6] The church site has a familiar circular Celtic llan but the building dates from the early English period.

The later tower, with one bell, was completed in 1887 in the Victorian Gothic Style by John Prichard.

A project will develop repair proposals and will include an ecology survey.
