St Materiana's Church, Tintagel

The Parish Church of Saint Materiana at Tintagel is a Church of England parish church in the Church of England Diocese of Truro in Cornwall, England, UK. It stands on the cliffs between Trevena and Tintagel Castle and is listed Grade I. The first church on the site was probably erected in the 6th century, founded as a daughter church of Minster: these are the only churches dedicated to the saint and though she is usually identified with Madryn, Princess of Gwent, it has also been suggested that the dedication could refer to Saint Marcellina, sister of Saint Ambrose.
