The monument to the Polish victims of the Mauthausen concentration camp was created in 1955. It was designed by Teodor Bursche (Bursze), a Polish architect and former prisoner of the Mauthausen-Gusen camp, and Stanisław Sikora, a Polish sculptor and medallist. It is a significant memorial by virtue of the fact that this camp was one of the key sites for the extermination of Poles as part of the so-called Intelligenzaktion. The monument is a substantial mausoleum, made of granite. It sits on an elevation, formed from the excavated earth. A granite staircase leads up to it. The mausoleum takes the form of an incomplete rectangle, in the centre of which is an urn made of black marble. Behind it is an engraved eagle with an inscription. On the front walls of the monument are plaques with text commemorating the murdered. The overall height of the mausoleum is 10.5 metres and the walls taper upwards. The sides of the memorial feature a cast-iron grille through which the urn is visible.
