‘Træfængslet’ (The Wooden Prison) is a collection of photographs made by Nick Geboers in the prison cells of the historical buildings of Kunstmuseet Tønder, part of Museum Sønderjylland in Southern Jutland, Denmark. The close-ups reveal marks, traces, glyphs, pictograms, and messages scratched, etched, and carved into the wooden walls, a collective evidence left behind by years of imprisonment. Geboers is an image-seeker fascinated by the rich history of photography. He also presents his own images in carefully thought out constellations. Switching between the position of an archaeologist and a visual author, he moves in a free space between hard and soft sciences.
