The Carnival of Oruro is a religious festival dating back more than 2000 years that takes place in the highlands of Bolivia. Originally an indigenous festival, the celebration merged with a Christian ritual around the Virgin of Candelaria, which takes place in February. The traditional ‘Llama llama’ or ‘Diablada’ became the leading traditional dances of the festival. It is one of UNESCO’s Intangible Heritage of Humanity. The modern festival demonstrates the ongoing pagan-Catholic blend common in the Altiplano region. The carnival starts with a ceremony dedicated to the Virgen del Socavon. Marching bands compete simultaneously in the greeting to the Virgin the grotto of Pie de Gallo. The highlight of the festival is the three day and three night parade of 48 groups of folk dancers over a four kilometre route to the sanctuary of the tunnel. In different regions of Bolivia and Peru, the locals wear colourful masks and dance to the rhythm of lively music, liberally inebriated by aguadiente, the local firewater.
