Historical Context: The 1916 Fire and Reconstruction

The Peace Tower's origins lie in the devastating fire of February 3, 1916, which largely destroyed the Centre Block of the Parliament Buildings. The fire consumed the original Victoria Tower, which stood on the site. Following the disaster, a national competition was held to design a new Centre Block, and consequently, a new tower. The winning design, submitted by John A. Pearson of Montreal, incorporated elements of Gothic Revival architecture, drawing inspiration from European cathedrals and castles. However, Pearson tragically died shortly after winning the commission. The project was then entrusted to Jean-Omer Marchand, Chief Dominion Architect, who oversaw the detailed design and construction.

The initial architectural drawings, created under Marchand’s direction, were crucial for coordinating the immense task of rebuilding. These drawings weren't simply about aesthetics; they were highly technical documents detailing every aspect of the structure, from the foundational bedrock to the intricate carvings of the tower's crest. Early drawings focused heavily on structural engineering, ensuring the new tower could withstand the harsh Canadian climate and potential future damage. These drawings, often drafted on linen using techniques like technical drawing, were the primary means of communication between the architect, engineers, contractors, and skilled artisans involved in the project. The drawings represent a pivotal moment in Canadian history, marking both a tragedy and a renewed commitment to national identity.
