Old Gymnasium, Kingston

The Old Gymnasium, also known as Building No. 25, is a significant historical structure located on the east side of the parade square precinct. Facing the athletic field, this long, gable-roofed brick building features large windows and classical details in wood and limestone, embodying a blend of functional design and aesthetic appeal. Its construction marked a pivotal development in the physical training and exhibition programs integral to Canadian military education at the college.

The Old Gymnasium is intrinsically linked to the evolution of RMC, particularly regarding the emphasis on physical training as a core component of military education. The college aimed to produce a "scientific class of officers fit for senior militia appointments" by combining a rigorous academic curriculum with a disciplined athletic program. The establishment of the gymnasium was a critical step in achieving this objective, providing a dedicated space for cadets to engage in physical training and athletic activities, which were considered essential for their overall development and preparedness for military leadership roles.

Architecturally, the Old Gymnasium is valued for its very good aesthetic design, characterized by classical symmetry, balance, and simplicity—elements typical of military architecture. The building's design emphasizes functional efficiency, with its structural system creating an interior column-free space that maximizes utility. The large, regularly spaced windows allow ample natural light to flood the interior, enhancing the suitability of the space for various athletic activities. These design features not only contribute to the building's visual appeal but also reflect the practical considerations necessary for a gymnasium.
