[2] As a commune, San Bernardo is a third-level administrative division of Chile administered by a municipal council, headed by an alcalde who is directly elected every four years.

The festival consists performances of traditional and folkloric Chilean music, dance, and singing, as well as competitions held at school, corporate, and community levels.

First proposed by professor Arturo García Araneda, a San Bernardino folklorist, the event centres around Cueca, Chile's national dance.

The event lasts for about 30 continuous hours and consists of a line-up of musicians, bands, or folkloric groups playing a thousand Cuecas for an open floor, where anyone is welcomed to partake in the dancing.

[11] Initially thought to be a fortress, the structure in the southern tip of the Chena hills has been denominated as a huaca (Quechuan Wak'a) a sacred place, a space of ritual use.

[12] Currently, the commune of San Bernardo lacks the resources to establish proper administration, maintenance, or security of the area, and Chena's Pucará faces physical abandonment, neglect and banalisation, including dismantling of walls and defecation on the altar.
