St. Afra has traditionally had a great devotion among the people of Girona for their relationship with the holy Narcís, patron saint of Girona. Since the XVIII century there is evidence of pilgrimages to the shrine.
According to tradition, in the early fourth-century the bishop St. Narcís and his deacon St. Felix arrived in the German city of Augsburg. They found accommodation in the house of Afra, a woman of pagan religion who had been devoted to Venus. Having known the holy Afra was converted to Christianity. The next day, the prefect of the city discovered the stay of the Christians at Afra's house. Because of it, Afra was burned alive in a post of the river Lech. The martyrdom was on 7 August 304, although in St. Gregory the festival dedicated to Afra is held on August 5.
St. Afra is invoked against hailstorms and healing of various diseases, especially of skin: fever, typhus, smallpox, measles, dirt, leprosy and various tumors.
The legend says that on the day of Afra's party something very strange happens when sunbeams sting the strongest. Strangely most cattle stay calm and quiet outdoors, confirming what the popular adage says:
"In de day of Afra, flies and bees doesn't sting"
