This beautiful and very sacred 15th-century church contains the tomb of St Ronan as well as a green wooden pulpit carved and painted with scenes from the saint's life in Brittany; note the blond keben (shrew) who attempts to stop Ronan from preaching. Ronan was an ascetic pilgrim from Ireland who established a hermitage in the woods here, around which the village eventually formed.
Also look out for the lovely statue of St Christophe (the patron saint of travelers), carrying the young Jesus on his shoulders.
