Abandoned Wonders
Web Urbanist features a post about 7 Abandoned Wonders of the European Union: From Deserted Castles to Retrofuturistic Factories.
The French "abandoned wonders" are deserted Metro stations:
Paris, France is notorious of late-running Metro trains due to frequent worker strikes – but perhaps less well known for its numerous abandoned Metro stations. Urban explorers manage to find their ways into some of these abandoned subway tunnels while others have been converted to new uses including (appropriately enough) official homeless shelters. Some of the tunnels can even be visited privately late at night in groups led by sanctioned rail-expert tour guides.
