The Senior School, Somerton Park
In 1897, the Marist Brothers were invited by Archbishop O'Reilly to open a school for boys in Port Adelaide. The Brothers opened two schools, Sacred Heart High School and Catholic Boys' Primary school. The first Principal was Brother Stephen Debourg.
By 1900, the Marist Brothers had begun to take in boarding students. During the first 10 years, Sacred Heart High School changed its location twice to provide room for the increasing number of enrolling students.
In 1914, Sacred Heart High School moved to the present location at Somerton Park. It was renamed Sacred Heart College and provided education for day students and boarders from Year 4 to Leaving Honours.
The early years saw Paringa Hall used for all aspects of school life which included classrooms, dormitories and dining rooms, and home to the Brothers. As the enrolment increased, a building program was commenced that eventually built up the teaching area around the central covered quadrangle.
The need for boarding places increased as well. In 1960, the Marian Wing was opened allowing the boarders to have their purpose-built space. Later a senior boys' boarding house was opened, followed in 1998 by a girls' boarding house.
The Middle School, Mitchell Park
St Joseph's College was first established in 1967 at Mitchell Park and catered for the younger boys (Years 5-10) of the local parishes.
The year 1977 saw a major change to the College and Catholic Education across the region. Sacred Heart College became part of the South West Region scheme and moved to become a co-educational Senior College catering for Years 10-12. Sacred Heart College Middle School (Boys Year 6-9) was also established at this time at the former St Joseph's College site.
Sacred Heart College today
In 2015, Sacred Heart College Senior at Somerton Park amalgamated with Sacred Heart Middle School at Mitchell Park under the leadership of Principal, Mr Steve Byrne.
In 2018, Marymount College in Hove (Year 6-9 girls) amalgamated with Sacred Heart College, comprising 3 campuses - Marymount Campus in Hove, the Middle School in Mitchell Park and the Senior School in Somerton Park.
From the beginning of 2019, Marymount Campus students and staff will relocate to the Middle School at Mitchell Park, which will be renamed Champagnat Campus, and will be a co-educational school for boys and girls in Years 7-9.
Sacred Heart College proudly remains a Marist school, is a member of Marist Schools Australia and is constantly developing the Marist Charism among its staff and students.
