Remembrance Day: Parliament Hill's Centre Block Stands As A Memorial To Fallen Soldiers

Across Canada people gather on Nov. 11 — the day the hostilities of the First World War ended in 1918 — to honour the courage and devotion of the brave men and women who made the supreme sacrifice for their country.

This sort of remembrance typically takes place at a local memorial, or cenotaph, where the names of the war dead are inscribed.

In Ottawa today, tens of thousands will gather around the National War Memorial for the official ceremony presided over by Governor General David Johnston, Tom Eagles, the dominion president of the Royal Canadian Legion and Prime Minister Justin Trudeau.

Ottawa's other memorial to fallen heroes

But there is another structure in Ottawa that also stands as a monument to Canada's fallen soldiers: the main building on Parliament Hill itself.

In the midst of the Great War, in 1916, a fire broke out in the Centre Block on the Hill, burning the Gothic-style building to the ground, sparing only the adjoining Library of Parliament.

As Johanna Mizagala, the House curator, describes in the video above, the government of Canada set out to quickly rebuild and devote the new building to fallen servicemen and women.

The symbols of remembrance on Parliament Hill are pervasive: John McRae's iconic poem, In Flanders Fields, is inscribed on the walls.

The walls of Confederation Hall, the main entrance to Centre Block, and the Hall of Honour, are decorated with commemorative plaques referring to the fire, the Fathers of Confederation and the Great War. Poppies have been carved into virtually every surface in the building.

But the centrepiece is the national shrine, the memorial chamber, a tribute to Canadians who had given their lives during the Great War in France and in Flanders.

John Pearson, the architect who designed the rebuilt Centre Block, described the room as a "sacred grove in the middle of the forest."

The floors and the walls of the room are made from stone Pearson personally collected from the main battlefields in Europe where Canadians perished. 

And the focal point of the chamber is the altar — a stunning block of British Hoptonwood limestone — which contains the Book of Remembrance that holds the names of over 66,000 Canadians who died during the Great War.

Today, there are six more altars around the chamber with separate books listing those who died in conflicts from the Nile Expedition to the Korean War, to more recent wars.
