Marian apparition
The tradition of the Marian apparition can be traced to the 15th century: In either 1434 or 1435, a fire destroyed the alabaster altarpiece. The replacement altarpiece features bas-relief representations of the Marian apparition. The image of the Virgen del Pilar venerated today also dates to this period. It executed in the late Gothic style of Juan de la Huerta.
