O come, O come to see the Christmas lights. Albuquerque is known for its Christmas decorations, and many residents decorate their homes with luminarias. These are small paper sacks with light provided from votive candles and weighted with sand. The luminarias have given Albuquerque a reputation as the City of Little Lights during Christmas. The luminarias are supposed to represent the lighting of streets to guide Joseph and Mary, but now people of all faiths put them out. They are primarily a Christmas Eve tradition, and have been a New Mexican tradition for hundreds of years.
