Every year since its inception in 1840, miracles are said to have occurred at the shrine of La Difunta Correa, and thousands of people have visited there to pay their respects.

Once the folk tale became known, the inhabitants of the nearby areas started visiting Deolinda Correa's grave, building after time an oratory that slowly became a sanctuary.

Cattle keepers first, then truck drivers, disseminated the figure of the Difunta, creating wayside shrines in many roads throughout the country, with images and sculptures of the Deceased.

In the chapel located on the top of the hill there is a life-size statue depicting the Difunta lying face to the heavens, with her child at her breast.

Visits to the Difunta Correa's Vallecito shrine take place during the whole year, but they are more numerous during Easter or at All-Souls' Day (2 November) and on dates special to truck drivers and gauchos, mostly in summer.
