Convite del Tio and Challa Oruro in Oruro
Convite del Tio and Challa gathers Oruro's mining communities before Carnaval to make offerings to El Tio, the underground spirit believed to control safety and fortune in the mines, followed by household and street blessings known as challa. Cigarettes, alcohol, coca leaf and confetti mark both rituals, which sit at the root of the devil imagery later seen in the main Carnaval parade.
Convite del Tio and the challa mark the moment when Oruro's mining communities formally invite the spirit world into Carnaval season.
