Carmelite monastery, Manjummel had been a landmark in the history of the Church in Kerala and that of the Eloor Municipality. Because it was here that the native Carmelite Religious started their life in 1874 receiving their habit from the Italian Archbishop of the place, the Most Rev. Dr. Leonardo Mellano . It is worthy of very special mention that this monastery had the unique greatness and fortune of having been the residence of the Archbishop of Verapoly ,for more than 25 long years even before the Monastery was complete .Dr.Leonardo Mellano ,the Archishop of Veraploy made it his residence and lived with us from 1871 until his demise in 1897 . His room, his chapel and his curia are still the revered portions of our monastery. This monastery was the source of consolation for all the people of this locality without caste and creed. It was the need of that time to impart elementary education for the people in and around this area,so the Carmelite fathers of this monastery headed by Fr. Michael de Santa Familia TOCD ,the then Superior of this Monastery took initiative to start an elementary school thus in 1916 the school began to function officially by name “ Guardian Angels’ Lower Primary School “ and got the Government approval.
After a long period of 50 years, this school received a new image with the establishment of a High School for the Girls.The credit goes to Rev.Fr. Stanislaus, OCD, the then Superior of the Monastery who took the initiative to start a High School Section .All the three standards namely VIII, IX, X had to be conducted together with U.P. Section until the existing building was to be constructed . The Congregation of the Sisters of Charity was so kind enough to work along with Fr. Stanislaus, OCD for the progress of the school, and for the smooth functioning the administration of the same was given to the hands of the sisters of Charity. For the last 30 years, they played a great role in the development of the school. We remember them with gratitude.

The idea of a CBSE School at Manjummel is originated from Mrs. Sushamma Teacher who was the Principal of GAHSS. She tried to get consent from Fr. Francis Thannikkappilly who was the Vicar as well as the Manager of the school. At last she made it successful to convince the father about the idea of starting a CBSE school.
