During the Day of the Dead festivities, the entire city of San Miguel de Allende seems to be concentrated around the main square. The preparations begin on October 30 when colorful flags are strung between the Parish gate and the trees of the main square, and hundreds of tourists from all over flock to the town eager to join in this tradition where both pre-Hispanic culture and Catholicism are mixed.

During All Saints Days (1 Nov) and the Day of the Dead (2 Nov), colorful altars are placed in the streets around the main square as well as in churches, hotels, restaurants and some shops. Thousands of photographs are placed on display in several contests, and competitions of carved pumpkins are held. Children eight years and up from the American community of San Miguel participate in a very original parade, dressed as skeletons in costumes called Catrinas, go out at night through the main plaza handing out sweets to all the kids.

These festival days are characterized by the smell of incense, the offerings on the altars, calaveritas (skull shaped carmel candy), marigold flowers, candles, prayers and music that accompanies the dancers of the pre-Hispanic dances.
