In 1692, the Manufacture royale des Grandes Glaces was established in the abandoned castle of Saint-Gobain, which gave the later glass company Saint-Gobain its name. The factory developed and in 1986 it still supplied the glass for the pyramid of the Louvre. In 1993, it was announced that the factory would close and on 31 December 1995 the last activity of this historic establishment disappeared.

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.

The Saint-Quentin war memorial is a unique memorial dedicated to the city's soldiers who fell in combat during different wars. The monument is located near the train station and features a large granite wall with three bas-reliefs depicting scenes from 1557, 1870 and 1914-19181.
