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.

In the year 2002, then Provincial  Rev. Fr. Paul Kattiparambil laid down the stone for a new building. LKG& UKG classes were already run in the building of HSS. Thus LKG, UKG and classes from I – VI standard started  in the new building.  Fr. Alex was appointed as the Principal of the school. Fr. Linus Puthenveetiil was the manager of the school. Fr. James also assisted in managing the school. Fr. Joshy Makkiyil was appointed as Malayalam teacher in the school.  After that Mr. K V Joseph a retired teacher from aided school came as the Principal of GAHSS.  He also helped a lot to solve the problems of the school.  Fr. Paul Kattiparambil was appointed as the Vicar of the ICC church and the Manager of the Schools.  Fr. David Rodrigues was appointed as Corporate Manager of all the aided schools of the Province and the administrator of GAHSS and GAPS.  Both the fathers worked hard for the development of the school and tried a lot to initiate affiliation procedures from the CBSE Board.  At that time more students started taking admission in the school.

On February 9^th 2011 Fr. Nixon Jose OCD took charge as Principal of the school.  As he took charge he tried to complete the entire procedures to get NOC from state government and get affiliated to CBSE Board, Delhi.  Mr. K A Nazeer, PTA President and Mr. Xavier chettan, also played a vital role in the actualization of dream of the school.

The school was getting fame among the people day by day.  The school’s physical infrastructural facility could not meet the rising demand for admission. 3.6 acres of land of Carmelite Monastery was taken on lease with due permission of the provincial council to put up a new building and to enhance the playground facilities.   At present the school is able to give good educational formation to the students who hails from middle class families. Mrs. Seline Seena Seemanthy as the Vice principal of the school made vital contributions for the wellbeing of the school. Fr. John Joseph was appointed as Asst. Principal of the school in May 2017. His remarkable contribution added a new wing to the leap of the school in its standard.

Being run by catholic minority its primary purpose is to provide a good all round education for catholic boys and girls; however non- catholic children are also admitted without any consideration of caste, creed and status. While keeping the Christian character of the institution, our school considers it as a duty to respect the religious beliefs of its other pupils. The school celebrates all the major feasts of different religions. The school is committed to the Academic Progress, Character formation and total development of the entire person undergoing training in our school. We hope that this venture of ours will lead the school to a bright future.
