In 1798, during the reign of King Canh Thinh of the Tay Son Dynasty, Catholicism in Vietnam faced severe persecution. Anti-Catholic edicts forced believers to flee from the royal court's pursuit. Under harsh conditions, many Catholics from the Dinh Cat area (now Quang Tri town) sought refuge in the wild forest of La Vang. Surrounded by disease, fear, and a perilous jungle environment, they placed their full trust in God and the Virgin Mary.
According to tradition, during a night of prayer under a banyan tree, believers witnessed the Apparition of Our Lady Mary, wearing a long cloak, holding the Infant Jesus, with two angels attending on either side. Our Lady comforted them, taught them to gather La Vang leaves to boil for water to cure illnesses, and promised to grant graces to those who pray in this place. This event not only brought hope but also laid the foundation for La Vang to become the largest pilgrimage center in Vietnam.

There are several explanations for the name "La Vang", but the most popular connects it to the dense jungle area with many "la vang" plants, a precious herb. Another hypothesis suggests that "La Vang" originates from the shouting cries ("la vang" in Vietnamese) of people seeking help when facing danger in the forest. Whatever its origin, the name has become a symbol of the protection and peace brought by Our Lady.
