Participants interested in history met together in Zamość in march 2015. They talked to seniors, wards of Zamojskie Voluntary Service Center. Interviews with seniors helped us to write their memories and to publish it in electronical and paper version. We saved life histories of witnesses of important historical facts from XX century (people whose life was marked by being prisoners in temporary camps, concentration camps and people deoprted as slavery workers to germany during World War II). We got knowledge which is not possible to learn at school or university. We have increased awareness of young people and local society about history of XX century.
