The Basilica of Our Lady of Good Health, also known as Sanctuary of Our Lady of Velankanni, is a Marian shrine located at the town of Velankanni in Tamil Nadu, India. The place is also a minor basilica of the Latin Catholic Church dedicated to Our Lady of Good Health. Devotion to Our Lady of Good Health of Velankanni can be traced back to the mid-16th century, attributed to three separate miracles believed by devotees to have been worked at the site: the apparition of Blessed Mary and the Christ Child to a slumbering shepherd boy, the healing of a handicapped buttermilk vendor, and the rescue of Portuguese sailors from a deadly sea storm.
