This sanctuary is linked to a pilgrimage of great local importance, held on Easter Sunday, and known as the Feast of Saint Águeda and Saint Neutel, and in the past also known as the Milk Pilgrimage. According to tradition, on this day farmers were supposed to offer milk to Saint Águeda, which was then sold at the door of the chapel by pilgrims. It was believed that this ritual would guarantee the fertility of the flocks, while the strong presence of milk as a symbolic element is linked to the torture process of Saint Águeda, during which her breasts were mutilated.
The chapel is the main point of the Rota de Sant'Águeda, which also passes by other religious monuments in the parish of Vila Nova da Baronia, such as the Chapel of Nossa Senhora da Conceição and the Igreja Matriz.
