The Redpath Museum's historic auditorium is home to many McGill classes and lectures. The lecture hall also contains four display cases, which have recently been renovated to contain a new exhibit: "Four Pillars of the Redpath Museum". Each of the four display cases contains a selection of artefacts and specimens that represent the diversity and historic value of the Redpath Museum's collections. These four cases present the Museum's Biodiversity, Mineralogy, Palaeontology and World Cultures collections.
The four display cases were designed and installed by Lauren McAusland, a McGill Undergraduate student, with the assistance of Museum Curators Anthony Howell and Annie Lussier, and Public Outreach Administrator Ingrid Birker.
