The verdict came just six months after another couple were fined for taking nude photographs of themselves at the same memorial at Vimy in northern France, which pays tribute to the 60,000 Canadians who died in the Great War.

In the latest ruling Tuesday by a court in the town of Arras, the married couple in their thirties, who put the video on a paying website, were also fined 500 euros each after they were found guilty of exhibitionism.

The symbolic one euro in damages was ordered because the Canadian state was a civil plaintiff in the case.

“The memorial has been known for a long time as a place where exhibitionism and voyeurism is common,” prosecutor Elise Bozzolo told AFP.

The memorial, two huge pylons that can be seen for miles around, was created in memory of the April 1917 battle of Vimy Ridge, a costly victory for Canada.
