Beautiful panoramic view of Lens and the surrounding area. Be careful when you climb onto the spoil heap during a storm, it's a real hair-raiser!

A superb monument commemorating the centenary of the Great War. It features nearly 500,000 names engraved in alphabetical order. Without distinction of rank, they come from soldiers of some forty different nationalities, all of whom fell on the front lines of Nord-Pas-de-Calais between 1914 and 1918.

The church dedicated to the Mother of God under the title "Notre-Dame de Lorette" rises in brilliant white and is visible from far away. But the brilliant impression is deceptive, at the latest when the visitor to the site realizes that they are in a huge military cemetery. Around 20,000 individual graves and a further 23,000 victims of war and tyranny buried in ossuaries are deeply disturbing.
