The Vimy Memorial is the most prestigious Canadian monument in Europe. It is located on the very site of the 1917 fighting near Vimy in the Pas-de-Calais region of France. Erected on the highest point of the hill, Hill 145, the objective of the operations that began on April 9, 1917, it overlooks the Douai Plain. In 1921, architect and sculptor Walter S. Allward (1875-1955) won the competition from the Canadian Battlefield Memorials Commission. The significance of the battles at the site and the favorable location at the top of the hill allowed Vimy to receive the most prestigious work.
