Paris Metro Station - Saint-Martin (closed)

Saint-Martin once had its own métro stop, situated between Strasbourg-Saint-Denis and République. It was closed at the beginning of World War II (September 2, 1939) and reopened upon the Liberation of Paris (August 25, 1944). However, it was soon shut down again — this time permanently, judged to be too close to its neighboring stations. Saint-Martin is the largest of all closed métro stations in Paris, and still features the old porcelain tiled advertisements on its walls. In recent years, it has been put to use to house some homeless souls during the coldest winter months.
