School is most definitely out at this abandoned university. The final lessons remain etched in chalk in the empty lecture theatres and experiments have been left to rot in deserted laboratories. For seventy-five years the science campus at Val Benoît University in Belgium was thriving, but now the classrooms and corridors are free from pupils and teachers. Instead, all 30.000 m² of the campus, formally the Science department, is encrusted with dust and decay. The site, now home to walls covered in cracked and peeling wallpaper and broken beakers, has been abandoned since 2005. “You could still feel the energy and buzz of the former times,” says photographer Stefan Dietze, 31, who captured these melancholic scenes.
