Near the church, located on Karl Marx Street, is the Polish war cemetery. Mostly soldiers killed between 1918 and 1920 are buried here (there are 183 of these graves). There is also a cross dedicated to the insurgents of 1863. In addition, 10 graves of soldiers from the 3rd Regiment of Mounted Riflemen stationed in Wolkowysk have been preserved, as in the interwar period the cemetery served as a garrison cemetery. The graves of soldiers from 1920 are situated in 5 rows, their orientation is opposite to that of the main monument. The monument bears the inscription: "To the heroes / fallen / for the Fatherland / in 1918-1920 / citizens of the city of Volkovysk". During the communist era, the cemetery was not completely destroyed, as the graves were covered with heaps of rubbish. At the end of the 1980s, the local branch of the Polish Cultural and Educational Society named after Adam Mickiewicz cleaned and renovated the cemetery. This work was continued by a branch of the Union of Poles in Belarus. In 1995. The Council for the Protection of Struggle and Martyrdom Sites financed the fencing of the necropolis. Unfortunately, the cemetery was devastated four times in the 1990s. In 1993, the Polish Graves Guard from Wrocław erected their cross at the cemetery. To the right of the central monument stands an oak cross with scythes crossed on it and a plaque with the inscription "1863 22/1". Next to the cross is a white Piast eagle. These two symbols were founded around 1995 by. Kazimiera Bućko from Gdańsk. In 1996, during renovation work on the façade of the church in Volkovysk, a marble slab, dedicated to the defenders of the Faith and the Homeland, fallen in 1920, was found, formerly located in the church cemetery. During the communist period this slab was dismantled and hidden away. On 15.08.2003, a new monument was erected in the military cemetery, on which this found slab was placed. Its inscription reads: "Ś.P. / Julian Sokołowski ppor. / Wiktor Paprocki ppor. / fallen in defence of faith / and Fatherland in 1918-1920 / Union of Reserve Officers / 1938 / Honour their memory / A.D. 2003 Compatriots". In 2000, another devastation of the graves in this cemetery took place, its effects were not removed until the following year. In 2019. Consulate General of the Republic of Poland in Grodno financed the restoration of the graves, consisting of cleaning and painting them.
