Jesus was due to be born. This was initially a very serious time, but over time Posadas Navidenas became a c community affair.
Nowadays friends, relatives and neighbours go to a different house each evening, carrying candles, and ask for shelter. The adults are given a strong punch to drink.
At the end of the journey, blind-folded children try to break the piñata, a brightly-coloured paper container filled with candy and/or toys and suspended form a roof, with sticks. There is also a nativity scene at the end of the journey.
