The church of St. Gwyddelan was built on the site of an earlier temple around 1500, and between 1570 and 1580 a south chapel was added to it. According to Sir John Wynn of Gwydir, who lived in the 17th century, the church was built by his ancestor Maredudd ap Ieuan, who purchased Dolwyddelan Castle in 1488 and rebuilt the church because was afraid he would be attacked by bandits in an old church far away. Around 1850, the porch and the new belfry were added.
The church from the beginning of the 16th century consisted of a rectangular nave without an externally separated chancel. Inside the presbytery, the nave was originally separated by an oak rood screen. In the second half of the sixteenth century, a chapel was added on the south side. It was quite unusually opened to the nave with two semicircular arcades supported by a central, cylindrical pillar. The church was topped with an wooden arch-braced truss.
St. Gwyddelan is a small and simple, late medieval rural church, but valuable due to its original form, without many significant modernizations. Noteworthy is the carved dragon placed near the north window.
