Eulalia of Barcelona was a young Christian martyr who lived in the Roman city of Barcelona during the late third and early fourth centuries. Born around 290, she is remembered for her courageous confrontation of the local governor, Dacian, during the persecutions led by emperors Diocletian and Maximian. At only thirteen years old, she faced severe torture for her faith and eventually died from her injuries. She is recognized as a saint and serves as a patron of the city of Barcelona.
