This is where the Somme River rises. Its name is traced back to Celtic origins and also gives its name to the department of the same name. At the time when Gaul was part of the Roman Empire, the river was called the Samara. It ends its approximately 245-kilometer-long river life in the Baie de Somme, where it flows into the English Channel.

As a memorial to the many dead, such a "MONUMENT AUX MORTS" (usually called a "Central Memorial" or "War Memorial" in German-speaking countries) is still very important today. "Now, Lord, you let your servant depart in peace, as you have said..." it says in the so-called "Hymn of Simeon" (Luke's Gospel, Chapter 2, Verse 29). However, the people who are remembered here did not depart in peace, but became victims of war and tyranny. Therefore, the term "fallen memorial" is now sometimes used instead of the "war memorial" that was previously common in German. In the French-speaking world, however, this aspect of commemoration of the dead has long been included in the most commonly used term "MONUMENT AUX MORTS". Regardless of language and nation, such a memorial has two important and at the same time everlasting tasks: -1- to keep the memory of the suffering and horror of war alive, -2- and to remind people of the need to maintain peace in the long term.
