Originally known as the Church of Saint Margaret, after the district where it was built, its foundation dates back to 1734. The building, of simple and sober architecture, features a small bell tower on the uphill side, which enriches its outline. The interior is also characterized by modest furnishings, in harmony with the atmosphere of devotion and contemplation. Over the centuries, the sanctuary underwent two major restorations: the first in 1896 and the second in 1949, works that preserved its essential and austere appearance.
The sanctuary is dedicated to Our Lady of the Chain, a Marian figure deeply connected to the concept of liberation. The faithful invoke her to be freed from oppression, anguish, slavery, and all kinds of personal, family, or social hardships. Traditional iconography depicts her showing a broken chain, symbol of victory over the “chains” that afflict human life. This powerful image expresses her ability to intercede for the faithful, bringing hope and consolation. The broken chain thus becomes a sign of trust and faith: an invitation to believe in the power and mercy of the Virgin, capable of loosening every bond that burdens the human soul.
