The Canadian National Vimy Memorial is a memorial site in France dedicated to the memory of Canadian Expeditionary Force members killed during the First World War. It also serves as the place of commemoration for First World War Canadian soldiers killed or presumed dead in France who have no known grave. The monument is the centrepiece of a preserved battlefield park that encompasses a portion of the ground over which the Canadian Corps made their assault during the Battle of Vimy Ridge, a military engagement fought as part of the Battle of Arras.
