Ste-Onenne (Tréhorenteuc)

About

The church of Sainte-Eutrope Sainte-Onenne, nicknamed the Grail Church, is a parish church located in the municipality of Trehorenteuc. This is the only church dedicated to a very local Breton saint, Saint Onenne. It is, however, better known for its elements and stained glass that blend the pagan elements of Arthurian legend with Christian elements, commanded by Abbé Gillard between 1942 and 1962.
