According to legend, the mortal remains of the apostle St James were taken to Galicia for burial, where they were lost. Eight hundred years later, a light led a shepherd, Pelagius the Hermit, who was guarding his flock at night, to the burial site. The shepherd reported his discovery to the bishop of Iria. The bishop declared that the remains were those of St James the Apostle and immediately informed King Alfonso II in Oviedo. In honour of Saint James, the cathedral was built on the spot where his remains were said to have been found. The legend, which includes numerous miraculous events, enabled the Catholic faithful to strengthen their stronghold in northern Spain during the Reconquista against the Moors, but also led to the growth and development of the city.
