This fonds is the primary repository for records that have enduring historical, corporate or community significance to Royal Roads University. University programs and departments, including staff and student experience, are part of these records. The holdings also include information on the historical buildings and the formal gardens of Hatley Park as they relate to Royal Roads University.

The fonds consists of records made or received by DND in the course of operating a series of military and naval training institutions at Hatley Park (Royal Roads Military College and its antecedents). The DND records were transferred to RRU Archives following the dissolution of the Royal Roads Military College in 1995. Record media include paper, 16mm film reels, photographs and graphics.
