History
Prince Alfred College
Prince Alfred College grew out of a Wesleyan Methodist resolve in 1867 to create a school “for the education of our sons”. Land was bought at Kent Town, and Prince Alfred, Duke of Edinburgh, laid the foundation stone on 5 November 1867 during his Australian tour, which gave the school its name.
