The centre is named after former student Marlene Carter, who graduated in 1963 and was the president of the Old Girls� Association from 1988 to 1998.
Mrs Carter joined Assistant Bishop of Perth Kate Wilmot, chairman of the board of governors Ian Curlewis and principal Lynne Thomson at the opening of the Marlene Carter Heritage Centre.
�I am delighted that its new home has been named in my honour,� Mrs Carter said.
The building underwent a custom-designed refurbishment and extension to house the school�s extensive archives collection.
St Mary�s archivist Stephanie Neille said she was excited to consolidate the school�s collection of photographs, minute books, publications, oral histories, maps and uniforms in the new heritage centre.
�The centre will offer a wonderful opportunity for curriculum participation and involvement from the St Mary�s community in the heritage of the school,� she said.
�With the approaching centenary celebrations in 2021, the centre will play a pivotal role in bringing the story of St Mary�s alive.�
