Bolivia's most beloved Marian pilgrimage rises from the central plaza of Cotoca, a small town east of Santa Cruz de la Sierra. Each December 8, over three hundred thousand faithful walk through the tropical night to venerate a wooden statue of the Immaculate Conception discovered inside a tree trunk around 1767. They call her Mamita de Cotoca, and her feast is the spiritual heartbeat of the Bolivian lowlands.

The devotion to the Virgen de Cotoca originates from the reported miraculous discovery of a carved wooden statue inside a hollow tree trunk around 1767, an event intertwined with a narrative of false accusation and divine vindication. Over two and a half centuries, this local discovery grew into the defining spiritual tradition of Bolivia's eastern lowlands.
Origin Story
Around 1767, in the countryside near the small town of Cotoca in what is now Bolivia's Santa Cruz Department, two mulatto field workers were falsely accused by their employer of murdering his foreman. Facing punishment for a crime they did not commit, the men fled with their families into the surrounding jungle. In their desperate flight, they came upon a hollow tree trunk and discovered inside it a beautifully carved wooden statue of the Virgin Mary, rendered in polychrome as the Immaculate Conception.
The men were devout Christians. They knelt and prayed, begging the Virgin to intercede and reveal their innocence. According to the tradition, at that very same hour, the actual murderer was seized by conscience and confessed to the crime. The falsely accused men were cleared, and the statue they had found became the object of immediate and growing veneration.
An alternate version of the legend describes lumbermen discovering the image while attempting to fell a tree, or fugitive campesinos seeing a mysterious radiance emanating from within a tree trunk on the night of December 15. In all versions, the core elements persist: a sacred image concealed within the living wood, discovered by humble people in a moment of need.
As miracles continued to be attributed to the Virgin's intercession, the Catholic Church authorized the construction of a shrine. A devout individual built the first chapel with a palm-thatch roof, and it was blessed on December 15, 1799. The first Mass was celebrated exactly one year later, on December 15, 1800. From this beginning, the devotion grew into the largest pilgrimage in the Bolivian lowlands.

Spiritual Lineage
The devotion has been sustained by the faithful of the Bolivian lowlands for over 225 years, passed from generation to generation as both religious practice and cultural inheritance. Dominican priests have served as custodians of the sanctuary, maintaining its sacramental life and pastoral care. In 2003, the Bolivian government formally declared the Festivity of the Virgen de Cotoca as Cultural and Religious Heritage of Bolivia, recognizing what had long been understood: that this devotion is inseparable from the identity of eastern Bolivia. The romeria has been described as the tradition that defines the spirit of Santa Cruz.
