Next to the church of St Grwst is Gwydir Chapel built in the early 17th Century by Sir Richard Wynn. It is the memorial chapel of the Wynn family of Gwydir Castle, and contains the empty coffin of Llywelyn the Great. He was buried at Aberconwy Abbey, but his coffin was moved to the new abbey at Maenan when the Cistercian monks were forced to move there by Edward 1. In the chapel there is also a 15th century stone effigy of Hywel Coetmor who fought at Agincourt.
