The Anglican Church of St Materiana in Tintagel stands on the cliffs between Trevena and Tintagel Castle - it is listed Grade I. The main structure of the church is believed to have been constructed in Norman times (lower late medieval), with some remnants of an earlier Saxon structure. The tower may be 13th or 15th century in date.

Saint Materiana was a 5th century Welsh saint and princess, who is patron of two churches in Cornwall and one in Wales. Saint Materiana was the eldest daughter of King Vortimer. After her father's death, she ruled over Gwent, with her husband Prince Ynyr.
