In 1887, the Foundress of the Institution, Mother Teresa of St.Rose of Lima, was commissioned to start a congregation of Carmelite sisters in Ernakulam, Kerala. 
The ministries of the congregation were confined to the state of Kerala until 1938, when a proposal was mooted by Dr.Colas, Bishop of Pondicherry to begin a school in Villupuram for its large catholic Anglo-Indian community. Mother Mary, the then Superior General condescended and out of the sylvan environs of emerald Ernakulam, ventured the pioneer quartet on their maiden journey to Villupuram, a typically torrid, tropical terrain on the western coast.
A sizeable house, La Fons bungalow with its three, acres of adjoining land belonging to the French Mission of Pondicherry was given to the sisters. La Fons is Sacred Heart today, a teeming academic hub.
