Mare Nostrum explores the experience of my grandmother during World War II as a French Resistant and more specifically her 4 years of imprisonment in Ravensbruck concentration camp as a political prisoner and her silence on her experience. This project reflects on the importance of the «devoir de memoire» (duty of memory) but also on the lack of recognition for the women who fought during the war. My grandmother kept silent because she realised that people who didn’t go through the concentration camp could not fathom the reality she lived in and what she saw. Avoiding her life as a young woman in critical times, the audio is a conversation my grandmother and I were having about her childhood and family.
