The College is named after St. Peter, the apostle of peace and harmony.St. Peter’s College is located at Kolenchery approximately 30 kilometers east of Kochi. Kolenchery was once a remote village with educationally backward inhabitants. The starting of the College was a boon to the rustic inhabitants of the locality. Besides producing thousands of graduates and postgraduates, uplifting the educationally backward people, the College has been the cause of ushering a new look to Kolenchery with many business establishments, banks, government offices and even a Medical College, and made it a beautiful township. The well-wishers of the College believe that the phenomenal growth of this institution is due to the invisible blessings of our Patron Saints, St. Peter and St. Paul. Ever since its beginning in 1964, the College management and the staff, through their consistent and untiring efforts, have produced citizens who excel as administrators, executives, clergymen, businessmen, doctors, engineers, lawyers and in a host of other professions.
