Don't miss this museum (also called the 'treasure house'), accessed upstairs from the rear of the basilica, where you can get a real close-up view of the Virgin and see the armfuls of unusual items gifted by the devout. There's also a room displaying the outfits she's worn through the ages (a new dress is premiered each year during the fiesta held in her honour) – however, the standout image is of the Virgin herself, with child, set upon a brilliantly burnished silver throne.
