At the North-East corner of the campus stands a four-storied building with wide verandas, large airy class rooms and a spacious ground. It is the new building that houses the century-old St. Patrick's School, a far cry from the decades before 1850, when the land on which it now stands, as tradition tells us, was a yard for elephants and camels. By the early 1890s, around 70 orphans were housed in small cottages here. In 1892 Fr. Anthony Mary Tabard began the construction of a grey stone building, noted for its pillared arches. This became the first school building for St. Patrick's. Fr. Joachim Mascarenhas was placed in charge of the school and the orphanage. In 1925 Fr. Tabard died and Fr. Leo Vanpeene, a veteran educationist, who for many years had been the Principal of St. Joseph's High School, took charge of the School and the attached Orphanage. In later developments, a High School section was added in the 1960s, and the school began to receive partial financial aid from the Government. The orphanage was separated from the school and housed in an independent building, while the whole school was rebuilt in the 1990s.
From the beginning, St. Patrick's School has catered to the needs of the poor. While all around, Bangalore has been developing at a rapid pace, it is astonishing to note that there are still a large number of underprivileged families living in harsh conditions in the centre of the city. St. Patrick's School aims to reach out to this neglected section of society, providing optimum standards of English education as well as all-round formation for growth and character development. A number of students are provided with educational assistance through the Church Education Fund. Extremely needy and deserving students are provided with accommodation facilities at the St. Patrick's Boys' Home. Facilities include a library and a sports field. St. Patrick's has made a name for itself in the field of sports and has produced a number of successful hockey players, footballers and cricketers.
