This is a narrative about Our Lady’s first apparition in history. It is accredited due to the fact that a Basilica has been built and there have been numerous astounding cures. During the Civil War in Spain, in the 1930’s, two aerial bombs were dropped on the shrine church, but neither exploded. Those bombs now hang on the shrine wall. Our Lady was still alive, living in Palestine, when she appeared to St. James, who was discouraged about a lack of converts in Spain. Jesus had been dead only seven years!

“On January 2, 40 A.D.., the Apostle St. James, the Elder, brother of St. John, sat tired and disappointed by the bank of the Elbo River in what is now Zaragosa, Spain. The people of the Roman province of Hispania (Spain/Iberian Peninsula) were not open and receptive to the Good news of Jesus and St. James was ready to give up his efforts to evangelize them. On that January day the Blessed Virgin appeared to James atop a column or pillar of stone. With encouraging words , she assured him that the people of Hispania would become Christians and that their faith would be as strong and durable as the pillar on which she stood. To remember the visit and promise of the Virgin Mary, the first Marian shrine was built around the pillar.
The pillar was made of jasper to mark the spot where she had made her appearance.
And James began to convert the pagans of early Spain.

“A poor beggar named Miguel Juan Pellicer from the town of Calanda, was unable to work because of an amputated leg. He had a great devotion to the shrine and frequently went there for help. The Virgin Mary answered his prayers by restoring his missing leg. After the word spread about this miracle, the number of pilgrims to the Church greatly increased.
Multiple church structures have occupied the site, each one larger than the one it replaced. Today, the Basilica de Nuestra Senora del Pilar, as it is formally known, includes 11 brightly tiled domes and is the second biggest church in Spain. Only the Cathedral in Seville is larger. Construction was begun in 1681 under the direction of King Charles ll.
