Corwen`s church is dedicated to St Mael and St Sulien who established a religious community in the area in the 6th Century. The present church dates from the 13th Century and has a Norman font, a dug-out chest and a 14th Century memorial. A prehistoric stone has been built into the porch. In the churchyard is the tall shaft of a medieval cross. The lintel above the south door has a mark said to have been made by Owain Glyndwr`s dagger when he threw it in rage from Pen-y-Pigyn, the hill behind the church.
