According to legend, the Virgin Mary appeared to St. James the Apostle when he was in Saragossa (Zaragoza), Spain. She spoke to him from the top of a pillar, which he interpreted as a sign that he should build a chapel where the column stood. The Feast of the Virgin of the Pillar is observed with special masses and processions, such as the Gigantes—giant cardboard and canvas figures representing Spanish kings and queens or famous literary and historical figures—and the cabezudos, or “big heads”—grotesque puppets with huge heads.
