In the military cemetery of Grudziądz rest numerous soldiers. The cemetery was created in 1920 by the chaplain of the Grudziądz garrison, Father Władysław Łęga. The first to be buried in this cemetery were Polish soldiers of the Grudziądz garrison, who died of illness or accidents before 1939. They make up the largest group of soldiers buried on this site. In the eastern part of the cemetery were buried the Allied prisoners of war who died in the prisoner-of-war camp of Grudziądz between 1940 and 1945. They rest in a common grave. These are mainly British, French, Belgian and Dutch soldiers. Several dozen prisoners of war of the Red Army, who died in the citadel of Grudziądz in 1942, are also buried there. Along the main avenue are also buried Polish servicemen and their families who served and lived in the citadel during the post-war period. In the northern part is the plot of the Red Army soldiers, who died mainly in the field hospital located in the citadel or in its immediate surroundings in 1945. In the south-eastern part of the cemetery is the avenue of heroes, dedicated to the memory of the soldiers of the 18th Pomeranian Uhlan Regiment murdered in the East or killed during the campaign of 1939. Plaques bearing their names, as well as trees, have been arranged here in their memory. A panel describing the history of the cemetery was installed at the cemetery's entrance in May 2023.
