Oratorio de la Difunta Correa, Religious shrine in Vallecito, San Juan Province, Argentina.

Oratorio de la Difunta Correa is a sanctuary in Vallecito, San Juan Province, Argentina, reached via National Route 141. It began as a cross on a hill and now comprises 17 chapels donated by devotees, whose names appear on plaques at the entrance doors. One chapel holds the remains of Deolinda Correa and a large sculpture of her lying with her child at her breast.

The sanctuary marks the place where Deolinda Correa died in the 1840s after following her husband, who had been conscripted during Argentina's civil conflicts. Over time, a folk belief in her miraculous powers grew, transforming the site into an important pilgrimage destination.

Devotion to Deolinda Correa is popular Catholicism rather than an official cult; the Catholic Church does not recognise her as a saint. Arrieros (muleteers) first and later truck drivers spread the devotion, raising roadside altars where bottles of water are left to quench the dead woman's thirst. Chapels donated by devotees carry the donors' names on plaques above their doors.

The sanctuary is located in a remote area and is best reached by car, with lodging and food options nearby. Visitors should bring appropriate clothing as the region is very dry with intense sun.

The chapels were donated by individual devotees, whose names appear on plaques above the entrance doors. One of them is said to hold the remains of Deolinda Correa, and inside stands a large sculpture of the dead woman lying face to the sky with her child at one breast.
