Basilica of Our Lady of the Pillar

The Basílica del Pilar is one of Spain's largest and most important Baroque churches, its four towers and eleven tiled domes forming an unmistakable silhouette along the Ebro riverfront in Zaragoza. Its founding legend is among the oldest Marian apparition accounts in Christianity: tradition holds that the Virgin Mary appeared to the Apostle James the Elder on a stone pillar on 2 January, AD 40 — during her own lifetime — making this one of the most theologically singular pilgrimage sites in the Catholic world. Construction of the current structure began in 1681, blending Baroque, Rococo and Neoclassical elements across its vast interior, which still enshrines the original carved image of the Virgin atop that same pillar. As patroness of the entire Spanish-speaking world, the Virgen del Pilar draws its largest crowds during the Fiestas del Pilar each October, when floral offerings and processions fill the plaza outside. Visitors can climb the towers for open views across the Ebro and Zaragoza's old town.
