The Urqupiña festival is annually attended by hundreds of thousands of faithful and national and international tourists, and it is one of the biggest events of popular religiosity in South America. Stretched out in preparations and aftermath over the entire month of August, the central days of the Urkupiña festival are August 14 to 16. While it falls on the same day as the Feast of the Assumption, and so mirrors other Marian celebrations elsewhere, Urqupiña has spawned a variety of offshoots in other parts of the world, such as Argentina, Virginia (USA), Spain, and Sweden, and wherever a sufficient number of followers of the Marian basilica of Quillacollo dwell.
