A luminaria is a light or little lantern, usually a candle inside a paper lamp shade, which is of significance among New World Hispanics at Christmas time.
In the U.S.states of New Mexico, Arizona and west Texas luminarias are made from brown paper bags weighted down with sand and illuminated from within by a lit candle and traditionally displayed on ChristmasEve. These are typically arranged in rows to create large and elaborate displays. Artificial luminarias, which are made of plastic and use light bulbs instead of candles, are also available. The hope among Christian believers is that the lights will guide the spirit of the Christ child to one's home. In recent times they are seen more as a secular decoration, akin to holiday lights, and have gained popularity in other parts of the country.
Santa Fe and Old Town Albuquerque are well known for their impressive Christmas Eve luminaria displays.
