If you walk past the ayuntamiento (town hall), you will reach this grotto where the Virgin is said to have appeared to two children who were led here by a dove in 1586. Within the clifftop cave is a flower-adorned altar in front of an image of the Virgin, plus some religious vestments and silverwork in glass cases. It's a poignant spot despite the barrage of visitors.
During the annual village procession on 8 September, the effigy of the Virgin is carried 2km up to the Ermita del Calvario, a tiny chapel built by Carmelite brothers. Black-iron crosses mark a short walking trail that leads up to the hermitage.
