The Zallense people are known for their popular culture and especially for their mythology. In Zalla, superstitions and beliefs in evil supernatural beings, sorcerers and witchcraft were widespread.
The hermitage of San Pedro Zariquete was a pilgrimage center against the evil eye and against demons. Thousands of devotees who believed themselves possessed by evil spirits in search of the corresponding exorcism passed through the year. The rite was to go to the chapel on the day of the saint on a path (while throwing handfuls of salt), and return on the other, so that the evil spirits did not re-enter the disemboweled person.[3]
