The paper examines the transgenerational transmission of knowledge in the neighbourhood of a place of mass murder that contains unmarked, uncommemorated mass graves. A study is based on a case of Krępiecki Forest. In this place located near the Majdanek concentration camp the Nazis killed, put into the ground and burnt thousands of victims. Many unburnt human remains are still at the place, in the ground. Nowadays it is a not-memorized-enough local forest situated between three villages, yet the memory of the victims still lives locally, passed between the local people. I examine the present residents of the villages and their attitude to that genocide. In my analysis the site is treated as an actant (Latour) interacting with the local environment, residents and institutions in a multidirectional network of relations (Archer). The main conceptual frame for this task is the theory of collective (Halbwachs, Assmann, Olick) and environmental memory (Domańska, Praczyk, Małczyński). I present the current possessors of memory, most of whom learnt about the genocide from their ancestors and neighbours. I explore their narration in the context of their parents' role in the event or its organizational and provisioning frame but also in the context of the environment. I ask how the landscape and ways of presenting it by direct witnesses of the massacre shape the perception of the area of present inhabitants of the place. The analysed data were collected during interviews but also by examining an artifact – an unpublished testimony of the genocide written down by a local miller, who writes not only about the events he saw but also about the present innocence of the landscape. Due to the illness, as an immobilized person, he became a guard of local memory. While researching interviews with his daughter I focus on the phenomenon of inheriting the witness' role and the mode in which it is handed down in a strict connection with the local landscape. This analysis may allow to understand better how memory can be co-determined not only by human-to-human relations expressed best in narration and communication but also by the environment and interactions with non-human actors.
