Las Posadas is celebrated in cities and towns across Mexico. Each evening during the festival, a small child dressed as an angel leads a procession through the streets of the town. The procession is primarily made up of children dressed in silver and gold robes carrying lit candles and images of Mary and Joseph riding a donkey. Adults, including musicians, follow the procession, which visits selected homes and asks for lodging for Joseph and Mary. Traditionally, the procession is always refused lodging, though the hosts often provide refreshments. At each stop, passages of scripture are read and Christmas carols are sung.
Mass is held each day after the procession, and, at the conclusion of the service, children break open piñatas filled with candy, toys, and, occasionally, money. The piñatas are usually crafted in the form of a star, which is said to have guided the three wise men of biblical tradition to the newborn Jesus.
