Saint Eulalia was the daughter of a noble family that lived near the city of Barcelona. She was a 13-year-old Roman Christian virgin who was martyred in Barcelona during the persecution of Christians in the reign of emperor Diocletian.
She lived during the persecutions under Diocletian. Eulalia left her home, entered the city and confronted the governor for his merciless persecution of Christians. Unable to dismiss the eloquent arguments of a young girl, Dacian soon had Eulalia stripped nearly naked and flagellated, which was followed by bloodier tortures that were not to cease unless she admitted the error of her ways. Resisting to the end, she prayed that God would take her to Heaven, and died of her wounds.
She is the co-patron saint of Barcelona.
