Saint Guirec (circa 6th cent.), according to oral tradition, was a Welsh monk who sought to establish a monastery in Celtic Brittany. In the region of Traou-Perros is where Guirec chose to found his new community.
A shrine first built in the twelfth century called L'Oratoire de Saint-Guirec (the Oratory of Saint Guirec) stands in the bay at Ploumanac'h with a chapel on the facing beach. Female pilgrims have come for centuries to call upon the prayerful intercession of the monk saint for their seafaring husbands' safety. Young women also come to ask Guirec's prayers that they would soon find a husband. The tradition of tweeking the nose of the saint's statue is said to encourage Guirec to acquire the blessing of a marriage within one year for the young pilgrim.
Saint Guirec is commemorated locally by the Roman Catholic Church in Brittany in conjunction with a traditional Breton Pardon ceremony on the eve of the Feast of the Ascension of Christ into heaven. 'Ascension Day' is celebrated the fourtieth day after Easter.
