 Ever since, the Carnival has been observed in honour of the "Virgen de la Candelaria" (Virgin of the Candlemas) or "Virgen del Socavon" (Virgin of the Mineshaft).The most important elements of the Carnival now occur in and around the "Sanctuaria del Socavon" (Church of the Mineshaft).Called Jururu (Uru Uru) in ancient times, the area that is now Oruro was a religious pilgrimage center of the Andean world.
