Probably in the 1950s, a Tchorek plaque, which said that "in 1943-1944, Polish patriots were repeatedly shot to death and burnt by the Hitlerites in this building", was installed on a wall of the burnt-out Wołyń Caserns, specifically on the east wall, facing Zamenhof Street. The plaque was lost in 1965, when Gęsiówka was demolished. Bogusław Kopka says, though, that during his visit to Warsaw in 1959, Richard Nixon, then Vice President of the United States, managed to lay a wreath in front of the main building of the former concentration camp.
