Our Lady of Guadalupe In 1531, Mary appeared to Juan Diego in what is
now Mexico City. She left a miraculous image of herself on the robe (tilma)
he was wearing which survives to this day. It can be seen in the magnificent
basilica in Mexico City which is visited by 20 million pilgrims per year.
Scientists are unable to explain the image. The medal is a reproduction of
the image on the tilma.
