In the 1860s, the Prussian Army established a training area for artillery at a wooded area near Lamsdorf, a small village connected by rail to Opole and Nysa. During the Franco-Prussian War, a camp for French prisoners of war was established here, which housed some 3000 French POW's. During the First World War, a much larger POW camp was established here with some 90,000 soldiers of various nationalities interned here.
