In Karlshorst, Berlin, three abandoned houses stand as ghosts of a fallen empire. Once home to families, they were seized in 1945 for Soviet military use, and later abandoned when the Russian Army withdrew in 1994 following he collapse of the Soviet Union. Their walls bear the traces of each forced departure, each change in power, each attempt to claim ownership.

and let no one be forgotten! explores what it means to possess, lose, and inherit contested spaces. Through interviews with historians, activists, and former neighbourhood residents, this audiowalk retraces the layered history of these houses and the political forces that have both shaped them and propelled them to international debate. Interwoven with these accounts is a semi-fictional narrative told from the perspective of a grandmother, who used to live in the neighbourhood when it was a restricted military zone, and her granddaughter. The audiowalk also encounters the houses’ current non-human occupants: raccoons that move freely through borders without deeds or ideology.

Blending oral testimony, archival material, and speculative fiction, and let no one be forgotten! unfolds as both an historical investigation and a meditation on ownership, belonging, and memory. Who has the right to call a place theirs? When empires fall, what, and who, remains? Could the houses themselves become monuments? Symbols of both loss and of reclaiming what was once taken?
