Roadside shrine
We see a lot of these little shrines or memorials along the road side. Sometimes they're quite elaborate, in memory of a deceased family member, or as a memorial to Difunta Correa who walked through the desert in the 1840s following her husband (a conscripted soldier during a period of civil war). She died in the process, but her new born son, whom she carried with her, survived and was found nursing at Difunta's breast, considered a miracle. She is now considered something akin to a patron saint of miracles.
