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.

In 1993, it was announced that the factory would close and on 31 December 1995 the last activity of this historic establishment disappeared.
