EVERY NIGHT IN A CORNER under the baroque clock tower in the Plaza de la Quintana, a hunched pilgrim appears. He stands life sized, and wears the traditional garb of the religious pilgrim: cloak, broad-brimmed hat, and a staff top-heavy with a gourd for water and the traditional scallop shell, which is the symbol of the pilgrim.
Upon closer inspection, the pilgrim is a trick of the light – and an unintentional one. His body is the shadow cast by the lightning rod pillar in the corner, and his staff is the shadow of the support column of the Berenguela clock tower. There are dozens of these lighting rods and hundreds of vertical supports in the cathedral exterior, but only one pilgrim. https://www.atlasobscura.com/places/shadow-pilgrim
