Imagined in the 19th century by the industrialist Jean-Baptiste André Godin, the Familistère de Guise is a unique place in France. Conceived as a true “social palace” for the workers of his factory, this architectural complex combines housing, collective spaces, and cultural facilities. Today transformed into a museum and visitor site, the place offers an immersion into the social and industrial history of the Hauts-de-France region.

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.

Completely constructed in white and black stone, the Basilica of Saint-Quentin is the second Gothic building in Picardy. Built between the end of the 12th and the end of the 15th centuries, it is best known as the burial place of the martyr Quentin, who gave it its name. Listed as a historical monument, the building boasts original architecture, with a porch tower over 34 meters high, a double transept, and a concentric choir. Inside, visitors are captivated by the ancient 260-meter-long labyrinth carved into the nave's paving. Stained glass windows installed at various times complement the artistic offerings of the Basilica of Saint-Quentin, particularly medieval stained glass windows in the 12th-century apse chapels. These depict episodes from the lives of the Virgin Mary and Saint Stephen.

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.

A very well-executed optical illusion in which the real world and the painted world merge into one.
