Our Lady of Guadalupe refers to a Marian apparition, a form of the Virgin Mary, that is highly venerated in the Catholic Church. According to tradition, the Virgin Mary appeared to Juan Diego, an indigenous peasant, on the Hill of Tepeyac near Mexico City in December 1531. She spoke to him in his native Nahuatl language and asked him to build a church in her honour on the site.

As a sign for the local bishop, Juan Diego gathered roses in his cloak, or "tilma," and when he opened it before the bishop, an image of Our Lady of Guadalupe was miraculously imprinted on the fabric. The image, which features a dark-skinned Virgin Mary, became a symbol of hope and unity for the Mexican people.

Our Lady of Guadalupe is considered the patroness of Mexico and the Americas. Her feast day is celebrated on December 12th, and the Basilica of Our Lady of Guadalupe in Mexico City is one of the most visited Catholic pilgrimage sites in the world. The image is regarded as a powerful symbol of faith, miracles, and the importance of Mary in Mexican and Latin American culture.
