History
Loreto College
Loreto in Adelaide began in 1905, when sisters of the Institute of the Blessed Virgin Mary (IBVM) opened a convent school in a small house on Sydenham Road, Norwood, with five students. Two years later it moved to a larger house on The Parade, and in 1921 it settled at “The Acacias”, a 5.25-acre property in Marryatville, where the ballroom became the junior school and the boarders slept upstairs.

St Aloysius College
St Aloysius traces back to 1880, when Irish Sisters of Mercy arrived in Adelaide from Argentina after unrest in Buenos Aires. That same year they bought George Dutton Green’s large house in Angas Street, behind St Francis Xavier’s Cathedral, and opened a convent and school called St Angela’s.
