The word posada means inn or lodging, and traditionally posadas are a celebration of the Christmas story. They take place on nine nights from December 16 to 24 and commemorate the Virgin Mary and St. Joseph’s search for a place to stay where Jesus could be born. Posadas in Mexico feature hot food and drinks, sweets, music, and piñatas.

Posadas in Mexico began as a way for the Spaniards to teach native people about Christmas. During the nine days leading up to Christmas Day, masses would include representations of Mary and Joseph. Following mass was a party where people were blindfolded before hitting a piñata with a stick, a representation of faith defeating temptation with the help of virtue. The fruits and sweets that poured out of the piñata represented the joys of union with God.

In time, posadas started to be held in neighborhoods and people’s homes, becoming a more familiar and tightly-knit occasion, as well as preparation for Christmas. At the beginning of a posada, people are divided in two groups, the ones “outside” representing Mary and Joseph, and the ones “inside” representing innkeepers. Then everyone sings the posada litany together, re-enacting Mary and Joseph’s search, going back and forth until they are finally “admitted” to an inn. After this tradition, the party proper starts.
