The National Memorial Site in Łambinowice, located on the grounds of former prisoner-of-war camps and cemeteries in the Łambinowice municipality in the Opole Voivodeship, is a significant landmark on the map of Polish historical memory. The contemporary camp areas have a history dating back to the 19th century, when a military training ground was established in the 1870s, which over time evolved into a system of prisoner-of-war camps, most intensively used during World War II. The camp in Lamsdorf was one of the largest German camp complexes in Europe, holding up to 300,000 prisoners of various nationalities, including significant numbers of Red Army soldiers, Poles, and others. An important architectural feature is the remains of camp structures, including barracks and a guard tower, which are part of the museum exhibition. The Museum in Łambinowice, housed in the former training ground commandant's building, presents the history of prisoners of war during World War II and the shelter provided for representatives of nations that fought against Germany. The Soviet Prisoners of War Cemetery, where approximately 40,000 prisoners were buried in unmarked graves, is another important monument of the site, highlighting the tragic fate of those who died there. The labor camp established after the war for the German population shows how the history of the region developed after 1945, and the commemoration of the victims of this period only became possible after the 1990s. The symbolic cemetery and monuments erected for this purpose stand as a testament to the past and a place for reflection on history. The National Memorial Site in Łambinowice is not only a valuable architectural site but also an important cultural and educational center that reminds us of the complexity of wartime issues and the fates of prisoners from various nations. This unique place not only preserves the memory of past events but also promotes historical awareness among contemporary generations.
