The Polish, Belgian and French prisoners of war who died between 1939 and 1941 in German Stalag IA Stablack were, in accordance with the requirements of the Geneva Convention, buried in individual graves marked with the names of the deceased and their nationality. They were buried in Stablack (today's Polish Stablawkj) and in Klein Dexen. Only Soviet prisoners of war were buried in mass graves.

The first Polish prisoner of war died on 16.09.1939. - he was Stanislaw Zebrowski, the last known burial took place on 17.05.1944. - Jan Brzozowski was buried then.

As late as 1971 the cemetery, although neglected, was still preserved in its original form. In that year the French authorities exhumed the remains of their 164 citizens (it is not excluded that during this exhumation the remains of some Polish prisoners of war were transferred to France).

In later years (it is not stated when), the entire site was razed to the ground and a memorial complex with a central monument was built on it. The memorial occupies about 3/4 of the former cemetery area.

In the 1990s, the identification of 48 Italian soldiers, whose stay in the camp was not known when the memorial complex was erected on the cemetery site, was carried out. The Italian diplomatic service was involved in this work. During the exhumation, objects belonging to Polish soldiers were found. An additional memorial plaque was then erected in Italian and Russian.

No census of those buried in this cemetery has survived. There is no information on the number of Polish burials. The district museum in Bagrationowsk contains only a plan of the cemetery, and the exhibition about the camp includes two exhibits: a Polish eagle from a cap and a button.

The memorial complex consists of a central monument depicting the prisoners of war and pedestals placed around it with the national emblems of the countries whose citizens rest in the cemetery. At the entrance to the cemetery, a concrete plaque measuring 155 x 93 cm was placed on a pedestal 50 cm high, with the inscription in Russian: "ИНТЕРНАЦИОНАЛЬНОЕ КЛАДБИЩЕ УЗНИКОВ / БЫВШЕГО ГИТЛЕРОВСКОГО КОНЦЛАГЕРЯ ШТАЛАГ 1А / СТАБЛАК / В лагере содержались польские, французские, / бельгийские и советские военнопленные-рядовые и / сержантского состава. / Захоронения производились в 1939-1944 г. Поляки, / французы, бельгийцы были захоронены в отдельных / могилах. Советские военнопленные погребены в / общих могилах-рвах. / В 1971 г. из 164 могил была произведена эксгумация / останков французских военнопленных." [translated as: "International cemetery of prisoners of the former Nazi concentration camp Stalag - I-A - STABLAK / in the camp Polish, French, Belgian and Soviet prisoners of war from privates to sergeants were held. Poles, French and Belgians were buried in individual graves, while Soviet POWs were buried in common graves. In 1971, the remains of French prisoners of war were exhumed from 164 graves"].

Around 2003, thanks to the kindness of the local government, religious symbolism was placed at the edge of the cemetery - two large wooden crosses (Catholic and Orthodox).
