Not far from the Piwowarych estate are the graves of the victims of mass executions carried out by the NKVD between 1937 and 1938. The site covers an area of 175 hectares; it was given the status of a memorial after the discovery there in 1989. 3 ditches - mass graves. The victims were covered with a mere 30 centimetres of earth.

Among the identified names of the victims are those of Poles repressed between 1935 and 1938 from the areas of eastern Belarus and Ukraine - the so-called Dzerzhinsk and Marchlevsk.

The uncovered graves are only a part of a large cemetery, as it is known that victims from the entire Irkutsk region were shot near Pivovary.

The memorial at this site was unveiled on 11.11.1989. It was the first mass burial site for victims of repression to be officially given the status of a cemetery in modern Russia. Since then, families of the victims have spontaneously installed plaques here with inscriptions and photographs of those shot and martyred in Stalinist prisons between 1937 and 1938.

The Polish commemoration in Piwowarysze was created in 2015 on the initiative of the Polish Cultural Autonomy "Ogniwo" and the Polish Consulate in Irkutsk. It took the form of a tombstone with an image of a weeping figure. Under the cross engraved on the slab was an inscription in Russian: "Such shame is before those who are no longer here for the deeds of those who brought so much misery. We remember, we ache." Below in Polish: "Spoczywajcie w pokoju".

At the end of April 2023, the Polish monument and the Lithuanian cross standing nearby were removed - a security official at this memorial complex reported that this act was done "in connection with the reconstruction work being carried out and the laying out of new alleys leading to the central obelisk", but a political background to this decision cannot be ruled out.
