Paris Underground. A second city lies under the sunlit one. A city of catacombs and quarries, subways and sewers with a life all its own.
Beneath the streets of Paris are hundreds of kilometers of tunnels. Besides the normal underground operations of a city there are abandoned quarries from the 12th century, deserted wine cellars and canals. An increasingly crowded Paris pushes its inhabitants into these forgotten underground spaces.
