The Wall of Valour is dedicated to the past students of Perth Collegiate Institute who sacrificed their lives in the First or Second World War. Erected in 2008, it contains the names, biographies and photographs of soldiers. The biographies were researched by students of Perth and District Collegiate Institute and they were presented with the Lieutenant Governor's Ontario Heritage Award for Youth Achievement for their contribution to the memorial.
On the left, above the names of the First World War soldiers, is a copy of John McCrae's poem, In Flanders Fields. On the right, above the names of the Second World War soldiers, is Major Alexander Campbell's poem, Prayer Before Battle. Major Campbell was a former student of Perth Collegiate who sacrificed his life during the Second World War.
