Our Lady of Good Health, also known as Our Lady of Vailankanni, is a celebrated Catholic title of the Blessed Virgin Mary believed to have appeared in Velankanni Town, Tamil Nadu, India. According to traditional beliefs, the Marian apparition is said to have occurred to a young boy delivering milk to the neighbourhood when the Virgin Mary, carrying the child Jesus, is said to have appeared. This apparition has not been approved by the Holy See.
The Basilica of Our Lady of Good Health erected by the Portuguese and the Indians stands at this site. The iconic depiction of the Madonna is unique in that it is one of two only icons where Mary is portrayed wearing an Indian Sari, while the other statue is said to have been buried with Aurangzeb, the Mughal Emperor . The basilica is known as a site for pilgrims from all over India and its assembly of multilingual prayers every Christmas. Source : wikipedia
