Seek out a marine graveyard in Brittany, a spectacular former coal mine in Germany's Ruhr basin, an abandoned hospital complex in Poland, ghostly plaster figures installed at a dilapidated church in the Czech Republic, closed-down prisons and asylums, deserted factories and more. For 10 years, Sylvain Margaine has traveled the world in search of these forbidden and forgotten places. An exceptional photographic report.
