On 6 August 2021 at 11.00, the celebration commemorating 30 Redemptorists and 50,000 residents of Warsaw’s Wola district, murdered in the first days of August 1944, began on the Męczenników Square at 49 Karolkowa street. The participants of the ceremony laid wreaths and bouquets of flowers, paying tribute to the civilian victims of the Warsaw Uprising. The Institute of National Remembrance was represented by its Deputy President, Karol Polejowski, Ph.D., D.Sc.

The square is located in the courtyard of the monastery of  Redemptorists. Its ceremonial consecration took place in 2000, and since then it has become one of the most important sites of remembrance of the victims of the Wola district massacre.

The extermination of the district was launched on Hitler's express orders as a reaction to the outbreak of the Uprising. The culmination of the slaughter took place on 5–7 August 1944, and the massacre was accompanied by numerous rapes, robberies and arson.

The organizer of the ceremony commemorating the victims was the Office for Veterans and Victims of Oppression, the parish under the name of St. Clement Hofbauer and Guardian Angels, and the Congregation of the Most Holy Redeemer.
