According to Christian tradition, Eulalia de Barcelona lived in Barcino in Diocleciano times. Many locals and inhabitants of Barcelona by then, fled town after this cruel Emperor mandara persecute all Christians. Today, these festivals are aimed, above all, to the smaller, and we will see why below. Eulalia was a teenage girl who escaped from the farmhouse where he lived with his parents in Sarria (currently neighbourhood of Barcelona) to confess their ideals religious and, thus, was martyred. The young girl was the victim of various torments, as the eculeo, and died on the cross, although there are doubts about the veracity of the narrative of his martyrdom. That’s why that during these memorable days, all citizens and attendees at the party pay homage to the brave Laia (diminutive of Eulalia), the girl who was revealed to defend their ideals. According to tradition, one of the torments that did pass consisted in throwing her rolling within a Coop full of broken glass by the street Baixada de Santa Eulalia, in which there is an image of the Saint in a chapel. Since then, this girl has been a symbol of solidarity, justice and commitment to youth advocacy for Barcelona and, together with the Virgen de la Merce, is patron of the same.
In addition, it is also taken by holy, insofar as it considers it the Roman Orthodox Church and Orthodox. Bishop Frodoino found his remains in the year 878, and moved them to the Cathedral. In the year 1998, craftsman Xavier Jansana makes rebirth to Laia, a giantess that gives life to this brave girl, and is dedicated to all the boys and girls from the city. The festivities include giants, the parades and the correfocs. The monuments dedicated to Santa Eulalia plate of the Pedro has the legend that Eulalia remained naked on a cross in this square, and the sky covered her with a light coating of snow.
