The Geelong Grammar Archives collection reflects and documents over 150 years of school life. The collections consist of images and memorabilia for all four campuses.The Schools of Clyde and The Hermitage Church of England Girls' Grammar School are also located onsite at Corio and in the purpose built archives repository, affectionately known as the “Vault”. History is everywhere at Geelong Grammar School, with heritage buildings, sculptures and significant trees all making up a kaleidoscope of heritage and a unique sense of place.

The Collection aims to be accessible via an ongoing digitisation project and through online exhibitions. Visitors can make an appointment with Fran Walsh to view the historical Michael Collins Persse Archives Centre at the Corio Campus.
