The Our Lady of La Vang procession festival is organized to commemorate the apparition of Our Lady and celebrate the Assumption of Mary (August 15). This is an occasion for believers to express their devotion, pray for peace, health, and blessings. The festival holds not only religious significance but is also an opportunity for the Catholic community to connect, share their faith, and spread traditional cultural values.
Every three years, the festival is held on a larger scale, known as the La Vang Congress, attracting hundreds of thousands of attendees. Even-numbered years usually feature a more solemn procession compared to odd-numbered years, and special anniversaries (such as 100 or 200 years) are organized on a grand scale.
