Our Lady of Guadalupe is a venerated image in Mexico City. In 1531, the Virgin Mary appeared to Juan Diego four times, healed his dying uncle, and told him to gather flowers “from the top of Tepeyac Hill, which was normally barren, especially in December. Juan followed her instructions and he found Castilian roses, not native to Mexico, blooming there. The Virgin arranged the flowers in Juan's tilma, or cloak, and when Juan Diego opened his cloak before archbishop Zumárraga on December 12, the flowers fell to the floor, and on the fabric was the image of the Virgin of Guadalupe.“-From Wikipedia
