Ch'utillos Festival is a symbol of faith and tradition among the Q'ara Q'aras, a prehistoric indigenous nation of Potos.
This festival is celebrated throughout the month of August. A mini entrance is organized before the big party which includes local kindergartens performing different dances wearing outfits made by local artisans; A parade led by party hosts selected by customs and uses and parishioners of both saints goes to the Sanctuary located in the Mullu Punku gorge on August 24th. It is a natural site that features rock formations, receiving thousands of pilgrims wishing for blessings and prosperity; a Quechua word for the youngster, Majtillo, is celebrated on the 25th and also the 26th as Thapuquillo, meaning questioner and the end of the festival.
Traditionally, this festival lasts three days. As a compromise for its survival, the current festival hosts go to the houses of the incoming ones on the second day. In celebration of the third day of the party, the current party hosts honor the Quechua word, "Cacharpaya", which means to release or culminate. Additionally, during the celebration of Mini Chu'tillos dancing parade, there is a generational cultural transmission. Those children who dance in that parade acquire knowledge about the Ch'utillos festival, ensuring its survival. At the native entrance, where actors share their knowledge with families and communities, the traditional music of the festival is preserved, disseminated, and taught.
Every year the municipal authorities of Potos organize, prepare and celebrate the Festivity, hoping that the new generations will know the significance of San Bartolomé. A formal education program is used to pass on knowledge about the Festival with the goal of safeguarding traditions and strengthening intracultural training. This event is extensively broadcast by the local and national press. A local community of researchers collects, records, analyses, and disseminates information about the festival.
Ch'utillos Festival grows stronger every year. In order to preserve and reproduce traditions, the State encourages a permanent and sincere dialogue among the various actors and communities. By incorporating the Ch'utillos Festival into the List of Intangible Cultural Heritage of Humanity, at an international level, the department's cultural identity and the importance of its intangible cultural heritage will be made visible, as well as the department's sociocultural development. There is an intragenerational transmission among the festivity hosts. Those who have already assumed the role of interns (as if they were godparents of a marriage) help the incoming hosts in completing the ritual in San Antonio, thus ensuring that knowledge is passed on.
