The Basilica of Our Lady of Good Health is located at the small town of Velankanni in the state of Tamil Nadu in southern India.
The Roman Catholic Latin Rite Basilica is devoted to Our Lady of Good Health.
Devotion to Our Lady of Good Health of Velankanni can be traced to the mid-16th century and is attributed to three miracles at sites around where the Basilica stands: the apparition of Mary and the Christ Child to a slumbering shepherd boy, the curing of a lame buttermilk vendor, and the rescue of Portuguese sailors from a violent sea storm.
These accounts are based on oral tradition and there are no written or attested records in support of them. The Holy See has not approved these apparitions.
The chapel was finally built by Portuguese sailors. More than 500 years later, the nine-day festival and celebration is still observed and draws nearly 2 million pilgrims each year.
The Shrine of Our Lady of Vailankanni, also known as the "Lourdes of the East" is one of the most-frequented religious sites in India.
