As the myth goes, it is said that Mary appeared to a boy and requested milk for her Son to which the boy readily agreed. Later, upon reaching the home of the customer, during inspection of his order, the customer found the milk pot to be full and was convinced that something miraculous had happened. Second time, it is said that Mary appeared to a crippled boy (son of a widow) in a place called Nadu Thittu. The boy is claimed to have offered her buttermilk and then be cured of his illness. The Catholics in the nearby town of Nagapattinam are said to have built the first shrine after being informed of the incident. In the 17th century, a Portuguese merchant ship, sailing from Macau in China to Colombo was caught in a hurricane in the Bay of Bengal. The sailors promised to build a chapel in the name of the Virgin Mary, wherever, they could reach safety. The myth is that the stormy sea became quiet and on 8 September (the birthday of Mary) their ship reached the shore of Vailankanni. Fulfilling their promise, the Portuguese sailors constructed a chapel at Vailankanni by transforming the earlier thatched chapel.
