The "Virgen de Urqupiña" festival is held annually on August 15. It is officially dubbed the "Festival of National Integration" and sees a host of different activities, ranging from an extended folkloric spectacle, over a central Mass, generally attended by the Bolivian president and other authorities, to a huge popular pilgrimage in the course of which people profess their Catholic faith, but also engage in rituals which are commonly seen as standing in an uneasy relationship with Catholic orthodoxy at best, or being outright pagan. People pray and offer promises to the Virgin of Urqupiña for money, health and luck. People greet "pachamama" (mother earth) with alcohol and food, burying or spilling it on the floor. A curious rite held on this festivity is extracting rocks from a hill near the sanctuary of the Virgin, whether the rock is big or small, it has to be taken home with the people who cracked the rocky hill to get it, who must return it the next year, as a symbolic act to ask the Virgin to lend them something (like health, money, luck etc.).
