In the forest south of Saint-Nicolas-Aux-Bois, we encounter a small sacred monument, which, based on its intention, can be classified as a memorial cross. The metal cross located at the top of the monument, surrounded by trees, is comparatively small in relation to the towering, divided shaft. The base of the "Croix Sézinne" consists of two (three if you count the transition) stone elements: a square shaft at the bottom, a slightly projecting, tapered connecting piece in the middle section, and above it, a round shaft that supports the actual cross.

Tergnier where Art Deco is omnipresent. Its most representative examples are Place Carnégie (classified as a historic monument), the Town Hall and the Fargniers church. The media library, a former station buffet, is a site that became historic with the arrival of Victor Hugo in 1870 who had his first meal on French soil there upon his return from exile. The bell tower of the Veltin school, visible from rue de la Famille Sauvage (Quessy-Cité), still indicates the time of the bombing which ravaged the city on the night of April 10 to 11, 1944. Seven tourist signs, located in the city to constitute the Trails of Memory, retrace acts of war or resistance during the Second World War which took place in the territory.
