St Mary's Church at Llanfair-yng-Nghornwy is of early medieval origin and has a chancel arch dating from the 11th or 12th century. It is mentioned in the Norwich Taxation of 1254. The chancel was lengthened in the 15th century, and a south chapel added in the 16th. The west tower was added in the 17th century, and the church was restored in 1847, and again in both 1860 and the 1930s. Cadw considers it to be "a fine rural parish church, incorporating significant early medieval fabric", and claims that it is "of special interest, therefore, both for its early origins and for the quality of its later detail," and it is Grade I listed.
