The history of St. Mary's Convent Inter College, Prayagraj, rests on the foundation of the Congregation of Jesus by venerable Mary Ward (nun) who founded the Institute in 1609, to cater to the education of girls, with the special emphasis on moral and spiritual foundation. Inspired by her zeal and enthusiasm, the CJ sisters came to India at an invitation from Bishop Anastasius Hartmann, to the then Superior General of the CJ sisters, Mother Catherine de Graccho, in Nymphenburg Germany. The pioneers to India, a group of five young sisters from Germany set out in 1853 across the oceans to the unknown strange land of India. After reaching Bombay (present-day Mumbai) by ship, they embarked upon a perilous journey across the vast peninsula of India in a bullock cart and reached Patna, where they founded the first house and school in India, St. Joseph's Convent High School, Patna. In the years that followed, these brave women and others who followed them worked whole heartedly to spread God'sKingdom in the Indian subcontinent , establishing new convents and reaching out to the poor and needy in the northern parts of India through the ministries of education , health care , care of youth and orphans. In the year 1866 ,Bishop Anastasius Hartmann intended to open a new Convent of the IBMV (Sisters of Loreto) in Allahabad and appealed to Mother General for more sisters. By the time the 8th Party of sisters arrived in India , the Convent and Boarding school at Phaphamau was almost ready. The sisters moved into the convent of January 1ih,[clarification needed] 1866.
On January 15, 1866 , the boarding school was opened with two pupils , Mary Elise and Nina Frizzone. Though the number of students increased gradually , since the sisters had to face endless problems in Phaphamau , they first shifted to Elgin Road in Allahabad , then temporarily to Lowther Castle and finally in February 1888 (or 1886), to 32 Thornhill Road (Maharishi Dayanand Road), where the school is situated today. The Roman Catholic Diocese of Allahabad had offered a piece of leased land, within the campus of St. Joseph's Cathedral, Allahabad to the sisters to build their school, where a spacious red - brick building had been erected. The original building exists to this day, and is considered one of the heritage buildings of the city on account of its unique architectural style. Around it many other structures have been constructed in the course of years to accommodate the ever increasing number of students. DELVING INTO THE PAST St. Mary's Convent is a name synonymous with education, values, culture and sense of responsibility.
